My new AF-S NIKKOR 20mm f/1.8G ED is on it's way!

Today is August 11, 2016. Tonight is supposed to be the peak of the Perseid meteor shower and it is predicted to be the best event for quite a few years (the next event estimated to be as good will be in 2099 - I don't know if I'll make it or not). 

It seems like just yesterday that I got my AF-S NIKKOR 200-500mm f/5.6E ED VR. In fact, it was May 3, 2016. Due to my never ending health issues this year, I think I've shot maybe a couple of dozen images with it. 

AF-S Nikkor 20mm f/1.8G
And yet here I am ordering another lens. This time I'm adding the AF-S NIKKOR 20mm f/1.8G ED. I am planning to go out tomorrow evening to use it to shoot some night sky and hopefully capture some of the meteors!

This lens has a much faster aperture than my other wide angle lens, the AF-S NIKKOR 16-35mm f/4G ED VR. I'm using that excuse to add another lens with a focal length that I already have, which I've been avoiding until this point.

Plus, this is a prime, for what that's worth.

I have not been completely unhappy with my 16-35mm f/4 for night skies, but I really got good results last year at the Grand Canyon National Park - North Rim when I used my very cheap AF Nikkor 50mm f/1.8D. That lens is pretty cool since it DOES have a physical focus stop at infinity; you run the focus into the stop and it's focused at infinity. Not beyond.

My 16-35 will continue to be useful, I imagine, for shots with more light and where I want to have more ability to compose with the zoom. I am planning to visit Yosemite National Park this September and I believe I will have a use for both of these lenses. I'm anxious to give it a try and will post more findings when I do.

Another part of my pleasure with that lens was the aperture. What I don't like about the 50mm f/1.8D is that it is a bit narrow. I'm hoping to get the benefits of a wide, prime lens to make up for it.

This lens doesn't have a stop at infinity focus but neither does my 16-35mm so I'm kind of used to it. It just means you need to address focusing in the dark some how (or pre-focusing the lens before it gets dark).

Similar to my 50mm, this lens doesn't have any VR (Nikon for Vibration Reduction). That seems weird when paying this much for a lens (about $800 from Adorama.com). But, that means there's no VR functionality to go bad either. 

The lens is one of the Nikkor "Gold Stripe" lenses, which they appear to put on lenses with the "Nano Crystal Coat", indicated by the "N" with the gold background. 

I've read a good number of reviews for this and some other lenses and the worst review I saw was from Thom Hogan - and it was still good. He just had a bit more detail about it's weaknesses. I don't see how I can go wrong with it - unless illness continues to keep me home bound!

Initial Review of Wacom Intuos Photo - Small

My wife got me this new gadget for my birthday. I have been wanting to try one, especially since seeing videos with Elia Locardi and how he claims to get his post processing done faster than with a mouse.

It does make sense to me, using a tablet rather than a mouse for drawing (including using brushes in Photoshop or Lightroom). I must have "hinted" as much since one showed up for my birthday this year!

My wife wasn't sure if I'd like it, or which one to get, and ended up getting me the Intuos Photo - Small, with the idea that I could keep it or exchange it if desired. I had no idea either which one to get. I know Elia is probably using their most expensive version since he's a Wacom ambassador.

I've had it about a week now, and have probably used it for 20 hours or so including a good 6 hour stretch working on a single image just to try different edits with it.. Here's what I think of it so far...


Small is the right size

I've been reading a lot of reviews and tips regarding the tablet, as well as watching YouTubes (phlearn has a couple of nice intro YouTubes). One thing I saw over and over was other people saying the small was the best size. I was surprised, as an American, because doesn't bigger mean better? Well, in this case, I don't think so. For me, and the other photography post processors that wrote opinions, small is better for a couple of big reasons.

First is the desk space. I don't have a huge desk top to put a big tablet on, especially if you orient it in front of the keyboard like a lot of the pictures you see. I have mine to the right of my keyboard (I'm right handed), and have enough space for it, my two monitors, keyboard, cup of coffee, and cup of pens and pencils. My desktop isn't crowded but with the larger size it would start feeling cluttered I think.

The second reason that people like the small size is because it works different than a mouse. With a mouse you typically have your wrist resting and scroll the cursor by dragging the mouse as far as you can without lifting your wrist, picking the mouse up and re-positioning it and then scrolling some more. Most mouse movements are accomplished without a lot of movement. The table works differently.

The tablet represents the surface area of your monitor. And if you have two monitors, the surface of both monitors is represented. To click something in the lower left corner means you position the pen at the lower left corner of the tablet. Then to click something in the upper right corner you must physically move the pen to the upper right corner of the tablet. Even with the small tablet you still must move your hand farther than with a mouse; you can't leave your wrist at the same place and do a series of scroll movements.

With the larger tablets you're moving your hand even farther. After a bit that gets tiring or annoying (I'm guessing somewhat - I have the small).

On the other hand, if you're doing actual drawing or graphic design work, which I don't, people say that the larger size is better for that. 


Set up and Installation



Wacom Tablet Properties
The tablet is pretty easy to install. It comes with a CD or DVD of their software applications. One application is their "Wacom Desktop Center" which allows you to get and install updates, visit their store, etc. The other application is the "Wacom Tablet Properties" dialog which is where you configure the tablet.

The configuration is fairly straight forward. This tablet has four configurable soft keys on the upper corners that you can assign. The pen has a couple of switches on it that you can also assign.

I went to their website, registered my unit, and downloaded the software directly instead of using the included media, as a lot of other folks mentioned. By installing that version you'll be up to date and will likely save the time of installing off of the CD just to find out you need to download the most recent version anyway.

The unit also came with some other Corel software that you can download but I doubt if I'll use it. It also has a coupon for some free prints which I might use, but the software wasn't why I wanted the tablet. If you're already using Photoshop or Lightroom the Corel software probably won't be very valuable.

The one issue I had was that once the table was hooked up (this unit is a wired USB version but you can add wireless  functionality for about $40), my Windows 7 operating system installed it's own tablet drivers and the operation was strange until I uninstalled the Windows drivers.

As I mentioned, this unit comes as a wired device. For my desktop configuration I don't think the upgrade to the wireless system provides any benefit so I doubt that I'll get the wireless kit. I like that it's available and that I didn't have to pay for that up front if I don't need it.


The Tablet and Pen

The tablet is well built, in my opinion. This version only costs about $100 or less so keep that in mind. It's not terribly heavy but it's feet are grippy enough so that it doesn't move around on my oak desktop. There is a cover on the bottom that hides extra pen nibs and has the cavities for installing the wireless unit and battery. They imprinted information too so you know what the various areas are for. The tablet comes with a locking cable attachment too!

There is a small LED on the top that lets you know it's connected. The LED shines brighter when it's working too, which is kind of nice. As mentioned before, there are two soft keys in each corner. I am still working on getting used to using them but they work. When you click on one of them a display pops up at the top of my main monitor letting me know what's assigned to the keys.

The pen is where I have an issue. There are two switches on it, one of which a lot of people recommend setting up as a "right click", which I did. When you use the tablet instead of a mouse you'll find you want that right click, for example to right click on an image file to select opening it with Photoshop. 

The pen that comes with this unit is hard plastic. It spins in your hand causing the switches to rotate. And, when the switches are where you want them (I've been pushing them with my thumb), it still feels akward. When I push on the switches it causes me to move the pen tip. Plus, it's very difficult to tell by touch which switch you're pusing on. I wish they had a bigger gap between the pen switches as well as a bump on one of the switches so you could identify them by touch easier.

I saw someone else post a tip where he added some gummy pencil grips to help. I have done that too. The gummy type work good because they stretch and are easy to trim. You'll want to trim them so they don't cover up the switches. I put a full size one on the upper end of the pen so that it rests where the pen lays in my hand. This tip helped a lot but I still find the pen akward. It doesn't feel natural or like a writing implement I would choose for anything else. But it's now more usable since it doesn't spin around. One more note - I wish I had grips that were not round so that when I lay the pen down it doesn't roll away.


So how does it work?

Again, I don't have a lot of time with it. I did work on an image for quite a while yesterday, watching YouTubes regarding configuring Photoshop brushes to be controlled by the pressure sensitivity. I'm still learning that aspect. 

What I can say, however, is that using the tablet is certainly different than using a mouse. I put my mouse up and am trying to get to where all I use is the tablet. It's hard to do certain things and I may not keep up this practice. I find it hard to copy and paste text. Even though I have a pen button set for a right click, I have a lot of problems with it. I configured one of the tablet soft keys to use as a right click and I have better luck with it. That alone is about enough to make me not want to use this as my sole pointing device but I'll keep working with it.

I also find it harder to pick up the pen and use it than reaching for a mouse. I don't know where to put the pen when I lay it down, for example to type. My desk is level but still the pen seems to roll away, like next to the keyboard, and then it takes more effort to dig it out than a mouse sitting patiently waiting for me grip it again.

The tablet supports various gestures similar to a laptop touch pad. I don't use a laptop so I'm not very familiar with that. I'm learning that and sometimes it's easier to use that way than using the pen. This is especially true if the pen has wandered away. Note that I generally have very little light on in my studio room and the unit is black - it can hide pretty easily!

One of the options the tablet has is to configure the mapping of the tablet to your monitors. I have mine set up to be "proportional" - the relative size of my two monitors is mapped to the tablet which means I'm not using the full surface of the tablet. I like that set up so far. You can even map into a smaller area to reduce your hand movements even more.

On the other hand, regarding actual post processing, Iike it better than a mouse. On the image below I used the brush to darken and add contrast to the clouds and the small hills in the background. You can see what is happening on screen as you draw with the pen, including how the pressure affects the size of the brush. It was much easier to draw along the hills than with a mouse. I used a brush to do some dodging and burning, and again, I really like how the pen works for that over a mouse. 

I can see that the drawing part of post processing is better. I just have problems with other controls, especially with cropping. But I'm willing to try to learn that. And, if you have the room on your desktop, there's no reason you can't have the mouse and tablet both hooked up. I have a feeling that I'll end up using that configuration. 

The bottom line for me after about a week is that I really like the unit for working with brushes in Photoshop (I haven't tried using Lightroom with it yet) but I find the other actions (copy and paste, right click, etc.) more difficult.

My Photography Bug

This has not been a good year for me health-wise. 

I started in January by losing a bit of eye-sight in my left eye. It's not permanent but it's so minor that the doctor's won't operate on it. The bad thing is that the default is right in the center of my vision. It really bothers me to read because I can only see about 2-3 letters of a word with my left eye. The good thing is that I use my right eye to look through the view finder of my DSLRs.

Then I started having sinus issues (well, I started those the previous November or December, they just got significantly worse starting in January. I went through various treatments with my allergist, then through 2 surgeries from my E.N.T. I just met with him again this last Monday and he's saying I may need a third surgery. Hooray, a surgery every 2 months! This has been the most traumatic issue - it's kept me from getting outdoors with my DSLR other than maybe half a dozen days for the first 7 months of the year. And, I just bought a new lens shortly before this last go-around. I've maybe taken 25 images with that $1,400 lens!

I had to have a dental crown installed. During the course of that I got lockjaw that prevented me from opening my mouth far enough to eat a sandwich. I couldn't get my index finger into my mouth. And, it made it painful to sneeze which my allergies tried to ruthlessly impose. I underwent about 5 weeks of physical therapy to resolve that issue.

Overall I've had maybe 5 weeks in 7 months where I haven't felt pretty crappy and missing work.

What I have realized, however, is that the photography bug is even more powerful than my other bugs. All I've though about is how depressing it is to not be out in the wilderness, even to the extent that I do it, and to not being taking photographs. And, I've thought about how important it has become to me to get outdoors and to try to shoot photographs since starting this hobby 3 years ago. I am very pleased with what this hobby has done for me. I had not been getting outdoors much for quite a few years before picking this photography hobby up.

And now, as August is just around the corner, I have made reservations to visit Yosemite National Park for the first time at the beginning of September. Barring another surgery, I am looking forward to the trip very much - to the exclusion of most other things! I know it's not the best time of year to go - I'd actually hoped to get out there in the spring - but I don't care now. Even if it's not the best time of year for photography I can enjoy the park and scout out photography locations. 

Don't get me wrong - I'm sure I'll still take a photograph or two. But since it's only about a 10 hour drive, there's no reason I can't get over there more. I just hope I don't have any other bugs that prevent me from going!

AF-S NIKKOR 200-500mm f/5.6E ED VR Review - Part 2

Well, I finally got out and shot a few frames with my new AF-S NIKKOR 200-500mm f/5.6E ED VR lens today! As promised, I'll post a bit of a review with some of my thoughts and experiences using it...

Note that in all of the photographs below I had the VR (Vibration Reduction) off since I was shooting from a tripod.

Nikkor 200-500mm f/5.6E

The Physical World


If you've read anything about the lens you've probably heard it's heavy and big. I certainly don't have anything else like it.

It's weird mounting the camera to it. The lens is heavier than the Nikon D610 (I haven't tried it on my Nikon D3200 yet). I had the lens sitting face down in the bag I'm using to carry it (an Amazon Basics Camera Backpack, which it about fills up). I mate the D610 to the lens and rotate the camera.

I carry the system by either the lens or the tripod mount on the lens.

When I get the lens mounted in my Manfrotto 468MGRC5 Hydrostatic Ball Head sitting on top of my Manfrotto 055XPROB tripod, it is solid. This ball head is paying off now! It's weight capacity of 26 pounds (12 kg) is really not being stressed and the ball head holds the system. The lens (~ 5 pounds) plus D610 (~ 1.6 pounds) is less than 7 pounds total (even with 2 SD cards!).

I did increase the "Friction" setting of the ball head to reduce the amount of play in the head when I loosened it - with that amount of weight the lens does tend to want to sag more. But when the "Friction" is set right, I find that the camera and lens are pretty well balanced. I had no problems at all. I did need to crank on the main knob more than with my other lenses to prevent the lens from drooping after letting go but once you realize that it was no big deal. I don't see a lot of love for this ball head but I sure like it.

Increase the Shutter Release Delay


I didn't get out my IR remote shutter release and instead just used the delay on the manual shutter release button. I noticed by looking through the view finder, however, that when I pressed the shutter release, the camera wobbled more than with my other lenses. I changed the delay from 2 seconds to 5 seconds to compensate - letting the camera settle down before releasing the shutter. I didn't notice the issue in my photographs so maybe it was actually still within the 2 seconds but since I was shooting a lake and desert hills, I felt the extra 3 seconds before the shutter release wouldn't hurt.

Using the wireless remote would probably work fine, unless it's windy. There was some breeze at the lake (Canyon Lake near Apache Junction, AZ), but not enough to visibly affect the camera. I didn't try cranking down harder on the ball head either - that's a chore for next time I guess.

Auto Focus


As I mentioned in a recent post, I use back button focus. I didn't have any issues using that with the shots I took. It didn't hunt around at all. It acquired focus with no questions asked and it appears to be pretty good. Granted it was a sunny, 97 degree Fahrenheit day in Arizona. I used an aperture of f/7.1 just to get off of the f/5.6 and to get a bit more depth of field.

How's the Focal Length?


I didn't get a chance to shoot any wildlife so I can't comment on that directly. What I can say is that from the Acacia picnic area I wanted to shoot the opening across the lake where the Salt River continues down stream. I couldn't get it all in the frame at 200mm. It made me wonder if the Sigma or Tamron with that extra 50mm at the short end would have allowed me to get the shot.

ISO 100 ■ 200mm ■ f/7.1 ■ 1/160s
Instead, I was able to compose the shot with the sheer wall on the right which is interesting.

In the photograph to the left I've purposefully left the full frame even though the water line isn't horizontal. I wanted to show the difference between the 200mm and 500mm focal length. This is the full image (okay, reduced to a max of 2040px wide for the web).

I did use some post processing in Lightroom, and did increase clarity as well as sharpening - just using Lightroom.

Here's a shot of those mountain peaks at 500mm, from the same location (I didn't move the tripod, just zoomed in to the 500mm focal length).

Nikon D610 + Nikkor 200-500mm f/5.6E
ISO 100 ■ 500mm ■ f/7.1 ■ 1/200s
I know these aren't great pictures; no one is likely to hang these on their living room wall. That's not the point. I wanted to see how the lens performed and how that 500mm could come in handy. I think I see opportunity here. I've shot landscapes in the past where I wish I could fill up more of the frame with a mountain, for example (like Humphreys Peak near Flagstaff, Arizona). This worked pretty good!

Basically, with a 200-500mm zoom, you should be able to increase the size of the subject by 2.5 times.

Lesson Learned - Update your Camera

One thing I figured out was that I needed to update my camera firmware. When I opened my files in Lightroom it didn't find the lens profile (well, I found out I also had to update Lightroom CC - it wasn't using the latest version of Adobe Camera Raw).

When I looked at the properties of the NEF files the lens information was missing.

I remembered that I'd seen updates to the camera firmware but hadn't bothered with them because I my lenses were already supported. This Nikkor 200-500mm only came out less than a year ago, though, and my cameras didn't know about it. I updated the Distortion Control software on my D610 but on the D3200 I had to do the Firmware and the Distortion Control software.

Now things are cookin'!

The Bottom Line


I'm happy so far with the lens - I think I'll keep it. I really wanted to try it to see if I liked it or whether I should send it back to Adorama but it looks like it's part of my bag now. I just wish it fit in the bag!

Another set of 200mm and 500mm shots for you to ponder. These don't have much processing at all and they both have the same processing. I just think it's interesting to see the difference in composition at both ends of the lens.

A short post about Back Button Focus

I am mainly a landscape photographer. My subjects don't often move around much. Consequently, for some time now, when I use auto focus, I've been using "Back Button Focus" on my Nikon D610. I think I've been using it since shortly after getting the D610. I like it.

Hey - why use Back Button Focus?


Most DSLRs (Digital Single Lens Reflex), as far as I know, allow you to press the shutter release half-way down so that the camera can focus on whatever is in it's cross hairs. Note that different cameras and different modes can cause the camera to focus at different areas of the image. I typically use a single focus and metering point so that's what I'll assume here.

When you press the shutter release half-way down and the camera locks in on the focus, you can then move the camera while still holding the shutter release half-way down in order to recompose your shot. For example you might focus on your significant other in the center of the shot and then pan a bit to get more of the Grand Canyon. Once you have the composition you like, you can press the shutter release the rest of the way to take the photograph.

That is pretty convenient, allowing the camera to focus on one thing and then to re-compose the shot after the camera has gained it's focus.

One problem with that technique, however, is that you have to keep the shutter release depressed half way in order to preserve that focus setting. If your finger slips off of the button you have to start all over. So what if you've panned a bit and then someone else steps into your shot? If you want to wait for them to leave, you've got to keep that button held down. 

In landscape photography I often want to focus on something, say a cactus in the foreground, and then re-compose. I may want to try 20 different compositions. And, I use a tripod for almost every shot I take (at least if I want them to turn out I do). Using the "normal" half-pressed shutter release can be a pain in the rear end (so can sitting on cactus).

Another issue with the "normal" focus is if you want to avoid camera shake due to the shutter release, for example if you use a remote release. If you have to hold the shutter release down part way and then trigger the shutter release it can cause unwanted vibration or motion into the camera.

This is where back button focus can help out...

What is Back Button Focus?


Back Button Focus allows you to configure a button on the back of the camera to use as a focus lock. It basically takes the place of the half-press action of the main shutter release button. You move your focus point(s) onto the subject as normal but instead of pressing the main shutter release button half-way to engage the auto-focus, you press the button on the back of the camera. Then, you can let go of that button - the focus will still be locked in. It won't change again until you press that back button again.

The cool thing about this is that you don't have to keep your finger on the button. The camera can even go to "sleep" - the focus of the lens won't be changed.

You can focus on your subject and take multiple images with different compositions and you won't need to focus on the subject again unless it moves. This is great for landscape photography where you can focus on a foreground object and as long as your camera doesn't move much (less than the depth of field) you can recompose without focusing for each shot. There is less time between each shot.

I use manual focus a lot too, but I still often will start with a press of the back button to get the lens either right where I want it or at least close and then I may focus slightly different for one reason or another.

Nikon D610 Back (Official Nikon Image)

How can I set up Back Button Focus?


Most DSLR cameras, at some level above the basic level, have a way to program one of the BUTTONs on the BACK of the camera to work as a FOCUS button. In the case of my D610, I use the "AE-L/AF-L" button, to the left of the rear thumb wheel.

You can usually find out how to set it up by doing a search on the web if your camera instruction manual doesn't outline it (or if you can't figure it out from your camera manual). Here's an example for the Nikon D610 Back Button Focus setup. 

Anything more you can tell me about this?


Luna the Barn Owl - most of him anyway
This subject is on my mind because of my outing at Arizona's Raptor Experience last weekend. I shot a number of images like this one - see anything wrong with it? When I got home I found a number of shots where the feet were cut off.

The problem was, I realized and figured out after shooting 400 pictures of raptors, was that I was setting my focus point on the bird's eye, using the back button focus, and not re-composing or even noticing that I was cutting off the toes of these fine feathered friends. 

I'll admit, it was a little nerve wracking at the shoot. I suppose the more you do it the better you get. But I was paying $190 for the trip to shoot the birds and that added some pressure. I rarely shoot animals successfully and that added more pressure. And the pressure prevented me from getting great shots. 

At one point, when we had some time with a flying hawk, I had to figure out how to get out of back button focus and to let the camera do it's job. Those photos turned out ever worse. I got zero usable shots of the hawk in flight.

My tip would be that, if you start using back button focus, it still is a good idea to practise the other auto focus modes of your camera if you have a chance. Especially if you know you're likely to be needing it at some point in the future.

Some Photoshop CC Post-processing Notes - Part 2

This is a continuation of my prior post: Some Photoshop CC Post-processing Notes - Part 1


Once I got the jesses removed I turned my attention to trying to make the owl stand out a bit more.

I started with a crop - using the "rule of thirds" guidelines in the Photoshop crop tool I reduced the image so that the owl's body was on the left 1/3 line. I decided to keep the entire stump in the image but cropped out some of the background on the right side of the image. By doing the crop I also reduced the amount of sky in the image. I left a bit more room above the owl's head than I did below his feet, in the hope of preventing the image from looking like he was being crowded on top.


Add a bit of Blur


Since a viewers eye tends to go to the brightest and sharpest objects in an image, I decided to blur out the portion of the stump on the right. It was apparently in the same focal plane as the owl's eyes because it was pretty sharp.

The way I blurred out the stump was to make another copy of the "Merge & Cleanup" layer and place it above that layer. An easy way to do that is select the desired layer and press [CTRL] [J]. This will create a copy and paste it in to a new layer above the one selected. I labelled this layer "Blur". 

With the "Blur" layer selected I clicked on the "Filter" menu, hovered over "Blur" and selected "Gaussian Blur...". Using the dialog I chose to blur the image quite a bit but left it to where there was some detail remaining in the target stump area. 


Mask
Then I added a black layer mask by holding down the [ALT] key while clicking on the mask icon.That will create a fully black layer mask, hiding the "Blur" layer. Next I used a regular brush with white selected as the foreground and about a 10% opacity to paint over the offending portion of the stump. This allows the blurred version of the stump to show through and give the overall effect of blurring out that area of the image. It's quicker than working with the original layer and trying to mask and blur that area.


Dodge and Burn


Following the blurring, I turned my attention to some lighting control. I'd already applied some lighting changes with Nik Color Efex Pro 4, but I thought I'd do a bit more. 

I decided to try to darken the sides a bit, but I wanted more darkening on the right side than the left since the owl was closer to the left side. I wanted to just add a "Brightness / Contrast" adjustment layer and use a mask so first I clicked on the "Blur" layer to select it to ensure that my adjustment layer would be added at the top of the layer stack and then clicked on the "Brightness / Contrast" adjustment layer icon.

I dragged the brightness down until I liked it on the edges. I also reduced the contrast just to kind of make the area less attractive to the eye although there wasn't much in this particular image that was affected. I added a mask to the layer. Then I selected a black foreground and used the gradient fill and the "Reflected Gradient" setting and dragged horizontally across the image to create a mask over the top of the owl, hiding the brightness reduction from that area. It did take some number of attempts to get the mask in the right position. I found I liked it best when the center of the mask was on the owl's beak.

Also, I had to go back and forth with the mask colors. If you end up getting a full black mask with a white area over the subject you can click on the mask in the layers and then press [CTRL] [I] to invert the mask.

I decided to try a bit more additional dodging and burning. In Photoshop I tend to follow similar steps as I just outlined. Create a "Brightness / Contrast" adjustment layer and bump up the brightness for a "Dodge" layer and decrease the brightness for a "Burn" layer. When adjusting the brightness sliders I look at the object I want to change and then adjust the slider more than necessary. Then you can add a full black layer mask and paint over the desired object with a white brush to add either the dodge or burn amounts. It's a little different than Lightroom where you can just adjust what you want the brush to do and then brush over the image.

I labelled my "Burn" and "Dodge" layers appropriately. I only ended up with a bit of a burning on that right portion of the stump to further get out out of the attention of my eye, and did a bit of a dodge on the owl's wings to bring them up a bit more. This could also have been done by going back to the camera raw object but since I'd made a copy of that and worked on cloning out the jesses, I'd have had to redo that step again if I wanted to adjust in ACR. This is a good pointer to try to make sure that you get the lighting right in ACR if possible.

Finally I grouped the three lighting layers into a layer group and labelled it "Dodge & Burn". I'm not sure you can see a lot of difference in these screen shots but here's where were at now:


Dodging and Burning layers applied

Note that the bottom Smart Object layer can be turned off if desired; the layers on top completely mask it. I don't think it matters one way or the other if it's on or not.


Some more Pop Please


I decided to try to add a bit more to try to make the image stand out.

First I added some more contrast using a "Curves" adjustment layer with a full black mask. I clicked on the little finger with arrow icon, clicked on various areas of the owl, and then raised or lowered the values to try to bring out additional contrast in those colors. I renamed the layer to "Contrast".

Next I added an overall Warming Filter layer by clicking on the "Photo Filter" adjustment layer and selecting the "Warming Filter (85)". I liked it but dropped the layer opacity to 85% to reduce the effect and make it a bit more subtle. I renamed the layer to "Warming Filter".

Note that the "Layer 1" in my Photoshop project is not used nor does it do anything. It's just there to make you wonder what magic I did in that layer. Did it work?

I liked the image at this point but decided to add a bit more vignette so I applied another "Brightness / Contrast" adjustment layer. I dropped the brightness again then added a fully white mask. I used another gradient fill but this time selected the "Radial Gradient" option, dragged a line to cause the center of the gradient to be centered on the front of the owl's face until I liked it, then adjusted the opacity to add a bit more of a natural "lens" type vignette although it wasn't exactly centered on the image. I just wanted to try to make the eye naturally look first at the owl's head.

After I did that I felt the image was a bit too dark over all so I did basically the opposite, adding another "Brightness / Contrast" adjustment layer but increased the brightness following up with another layer mask to not wipe out the vignette I just added. At that point I felt I was done! Here's the final image again in Photoshop:

Final Output

The last step is to output the results for whatever purpose desired. I like the Nik Sharpener Pro 3 Output Sharpener. It offers a lot of control although it does require playing around with it to get it the way you want. Again, the plugin allows you to fine tune areas that you want sharpened and to avoid adding sharpening to areas you don't. After blurring the stump on the right why would I want to sharpen it now?

As mentioned earlier, the plugins work on TIF files. The process I'm using right now (I'm sure I'll learn a better way in the future) is to export my edited image from Photoshop as a TIF copy (as opposed to saving with layers). I export at the full size of the image.

Next I open the TIF file in another Photoshop tab. I convert the image layer to a Smart Object so that I can re-edit the settings I'm about to apply if I want to.


Nik Sharpener Pro 3 Output Sharpener
I open the image with the Nik Sharpener Pro 3 Output Sharpener. Then I zoomed in to 100 % on the owl's eye. That's the part I want to have sharp but not too sharp. I have some presets I've saved, the main one I start with is where I've set the "Adaptive Sharpening" slider to 20%, the "Output Sharpening Strength" I left at 100%, and the "Structure", "Local Contrast", and "Focus" controls I have at 3% each. I find this is a decent starting point. 

Note that when you open Sharpener Pro 3 it will use the most recent settings. To reset everything you can click on a different preset and then re-click on the one you want to start with.

Sharpening is a matter of taste and experience using the tool. I sharpened this image for full size display purposes and saved it as a JPEG. I have found it best for met to then open that image in the Windows image previewer and look at it. Sometimes I need to make additional edits and save as JPEG again until I get a version that I like.

But that's not the end...

If you want a different size of the image it's best to apply the sharpening to that size of image rather than resizing an already sharpened image. That is why I do the intermediate step of saving the TIF. After exporting to the full size I save a copy of that Photoshop file (a PSD file). Then I resize the image to the size I want (generally one where the longest side is at 2048 pixels for the best uploading to Facebook). 

After you resize you need to re-apply the sharpening plugin. It's probably best to completely delete the original sharpener layer and start over with it just to ensure it's working with the new image size. Once you've sharpened the new image size and exported it as a new JPEG, you're done! Again, here is the final version:

Some Photoshop CC Post-processing Notes - Part 1

I thought my post processing of this photo turned out pretty good so I thought I'd share what I did. 


Luna the male Barn Owl
Arizona's Raptor Experience

I am using Adobe's Creative Cloud Photography Plan (I also want to point out that I'm not affiliated with them or any other product that I mention, unless I explicitly mention it, and of which at this time there are none to mention). Since I installed the Google Nik Collection of processing plugins, I've mainly been using Photoshop and that's what I used for this image - Photoshop CC and various Nik plugins. 

First, I almost always shoot RAW, as I did for all of the images at this shoot. Without getting in to that discussion, the RAW format allows you a much greater latitude of adjustments in post processing. The first step in working with a RAW file is to import it using a RAW converter. I used the Adobe Camera RAW (ACR) converter for this file.


Adobe Camera Raw


I've created a few pre-sets in ACR, which are basically everything set at zero with these exceptions: 

  • On the "Lens Corrections" tab, I check the "Enable Lens Profile Corrections" check box on the "Profile" sub-tab and the "Remove Chromatic Aberration" check box is checked on the "Color" sub-tab.
  • On the "Camera Calibration" tab, I selected a few of the "Camera Profile" settings and saved each one as a different preset. I did this so I could go through them on the "Presets" tab.
  • For my Vivid2 preset, on the "Basic" tab, I also set the White Balance to Daylight and on the "Tone Curve" tab I selected the "Medium Contrast" curve. I found that I used these settings often so saved them as a preset.
By having everything else at zero I know I'm starting with a clean slate.

Here's what the RAW file looks like as shot. This version has no processing other than converting to JPEG and re-sizing.


Straight Out Of Camera
(SOOC)
In Camera Raw I normally do some spot cleanup for dust spots but since this was shot at f/4 the dust spots weren't visible anyway. Nice!

I adjusted the shadows to bring up the wing but that's about it. I planned to do the initial shapening and noise reduction in Nik so left those tabs alone and opened the image as an object in Photoshop.

By opening the image as an object you can go back and adjust things in Camera Raw as well as the other adjustments I planned to make with the Nik plugins.


Nik Plugins


Following the Nik plugin suggested workflow, I planned to do the "pre-sharpening" with the Nik Sharpener Pro 3 Raw Presharpener. I'll have to admit that using the Nik plugins adds time to a workflow because it takes time to open them up. They have to convert the files to .TIFs to work with them and each plugin has to go through that process. On the positive side, for this plugin, you can more easily control what you want sharpened and what you don't. 

I didn't want to sharpen the sky or that background in the lower left. By using the control points I could apply the initial sharpening to my subject only and to not try to sharpen the blurred areas that I paid more for a lens that would try to blur things out in camera.

If you don't use the Nik plugin you should at least always use the "Masking" slider in Camera Raw or Lightroom to control where sharpening is applied by hitting the [Alt] key as you move the slider and adjusting it until only the desired edges are highlighted in white. This is a trick I only found out about in the last few months but it means you're NOT applying sharpening to the entire image but only the edges that need it.


Nik Dfine 2
Next I used the Nik Dfine 2 to do a slight bit of noise reduction. Similar to the pre-sharpener, you can use control points to control what you want noise reduction applied to. 

I've just recently (within the last few weeks) stopped worrying about noise reduction much but I still like to apply it to large areas of the same or similar color such as the sky. I used control points to prevent or reduce noise reduction on the owl but I did use it for the sky.

You can see that the owl is masked (black) which means that noise reduction is NOT being applied in those areas. Noise reduction works by blurring pixels. Even if it's slight, I don't want to blur the details on this subject with noise reduction. I didn't really see any noise on the owl anyway but by masking him I know that there won't be any blurring of the detail in his feathers due to the noise reduction.


Nik Color Efex Pro 4
Since I didn't feel I needed to adjust the general lighting much I didn't use Viveza 2 and instead went straight to Color Efex Pro 4. Note that Viveza 2 can also be used to add "structure" to an image, basically to bring out additional detail, in addition to allowing you to do lighting and color adjustments.

I also didn't feel the need to do a lot of color effects but I did some. I used the "Detail Extractor" filter to help bring out more detail in the feathers. I used the  "Polarization" filter to darken the sky a bit as well as to bring out the blue in the sky. This filter also provided a bit more contrast and saturation to the owl. Finally I used the "Darken / Lighten Center" filter to add a bit of a vignette, but I ended up doing even more directly in Photoshop later.

Those are the initial edits I did with the raw file and the Nik plugins. You can probably see in the image in the initial images that Luna has the leather "jesses" around his feet. My next step was to create a copy of the smart object and put it in to a new layer to begin working on that. You can't edit a smart object directly as far as using the healing brush.


Adobe Photoshop Clone and Heal


By clicking on the smart object layer and selecting everything ([CTRL] [A]) you can make a new copy by pasting the copied image ([CTRL] [V]). This will create a merged copy on top of the smart object which will allow cloning out items such as the jesses. Note that I took the time to re-label the new layer to "Merge & Cleanup".

After some time I got an acceptable removal of the jesses as shown below. I think it's okay - and I don't think most people are going to know what the legs truly look like without the jesses nor will they concentrate on that portion of the owl as much as his head. Here's a shot of Photoshop up to this point. I'll continue with the rest in the next post.
