Why on earth would you be shooting at 1600 ISO in broad daylight? I don't understand this! High ISO numbers are for low light situations, not just because the camera is capable of high ISO. Daylight shots should be shot with no more than 100 or 200 ISO at the most.
Agree with you Jeff: the greenesh tint came from color fringes of camera body sensor. This is known issue with D7000 and the other beginner models (5100, 3100... ). D300 and other advanced amateur models are much better in this.The greenish tint around his right eye is sort of weird...overall it is a decent snap...good framing for the focal length...adequate shutter speed...nice focus and DOF...but the ISO is way high for a daylight photo IMO...perhaps this is why you have the greenish hue bleeding all over his eye...bet it comes from the green OOF patch just beyond his eye...I would say high ISO sensor bleeding noise around the eye...it would be nice to see a similar shot done around 200 ISO. You have to really watch it with these newer sensors...I see this kind of thing in many D7000 shots...maybe it is just a bunch of pollen he has rubbed all over his eye though...at any rate he looks to be sort of disgruntled but I imagine being stuck in a zoo somewhere would do that to just about anyone.
It's a good shot though...
No way, Jeff: the 16-85mm has max aperture 5.6 at 85mm. And Phillip set lens wide opened already. And, if he could open f/4 intead of f/5.6, he gona loose some DoF, not gain.You probably could have got away better with F4, 800 iso, and 100-125 shutter speed...less noise...you'd gained a tiny bit of DOF too...
The greenish came from shooting through the glass AND it is an issue of the color fringers in image sensors. This photo also taken through the glass with an SB-800 on-camera filled:I thought that the greenish hue around the ape's eye was from shooting through the glass, but it also could be an issue with the D7000.
One more thing. If the photo was B & W, I think it would be much better since the green behind the gorilla is very distracting. Give it a shot and see what you think. Just desaturate it.
Kong is the king!
So when you going to the zoo again sir? I think you oughtta document that ape's expressions...I bet that would make for some cool snaps...
