This image, the original from which yesterday’s featured image (see same here) was created, was made with the hand held Canon EF 200-400mm f/4L IS USM Lens with Internal 1.4x Extender (with the internal TC in place at 490mm) and the Canon EOS-1D X. ISO 1600. Evaluative metering +1 1/3 stops: 1/500 sec. at f/9 in Av mode. One sensor to the left of the central sensor/AI Servo Rear Focus AF on the nose of the iguana active at the moment of exposure. Click here if you missed the Rear Focus Tutorial.

Why the Eyes Had It
Note that the original capture above was too dark, and note that the Marine Iguana blinked just as I depressed the shutter button. See the 4-second animated GIF below for the before and after images.
In yesterday’s blog post here, I asked:
Do you see anything Photoshop fishy about the image above?
Why +1 1/3 stops of plus compensation?
With the active AF sensor on the tip of the reptile’s nose, why are the eyes sharp?
Kudos to Tom Roper who commented as follows:
The only ‘fishy’ thing I notice is the dust spot near the green triangle on the upper right side.
q: why add +1 1/3 exposure compensation?
a: because the sand averages lighter than middle exposure so you need to add light to expose the iguana.
q: why are the eyes sharp if the AF sensor was on the tip of the nose?
a: as subject distance increases so does depth of field
Tom has eagle eyes. The small dust bunny that he noted was removed from the optimized TIF file. He was of course correct on the exposure but the original capture above shows that I did not add nearly enough light; + 2 would have been much better. He did a good job on the last question also but should have added that I had stopped down from wide open (f/5.6) to f/9.

The Image Optimization
I lightened the image one-half stop during conversion in DPP by moving the Brightness slider to the right to 0.50. See the DPP Raw Conversion Guide to learn why I convert in Canon Digital Photo Professional. Next I painted a Quick Mask of the green triangle over the iguana’s head, put it on its own layer, and moved it to the right side of the frame. Then I painted another Quick Mask, this one of the clean sand, put that on its own layer, and used it to cover the offending green triangle.
After doing some Eye Doctor work on it, I painted a Quick Mask of the creature’s open left eye, placed that on its own layer, and flopped it. Then I reduced the opacity of the layer to make it easier to position it on top of the closed right eye. Next I transformed and warped the layer to match the size and orientation of the closed eye before raising the opacity back to 100%. Adding a Layer Mask allowed me to paint away everything but the new eye. Clicking the eyeball on and off revealed a perfect job.

Beach clean-up was done with the Patch Tool and the Spot Healing Brush. After selecting the iguana with the Quick Selection Tool I applied a layer of my favorite 50/50 NIK filter (50% Detail Extractor plus 50% Tonal Contast). Note the spectacular improvement afforded by the Detail Extractor portion of the filter. A nice crop from the bottom was the finishing touch.
Everything above and tons more is covered in detail in my Digital Basics File. Digital Basics is an instructional PDF that is sent via e-mail.
