I took this picture this evening in my back yard. We have a healthy population of lizards, and they prowl the vines growing along the fence. This guy had just emerged from the vines and jumped onto the fence and he was in the process of turning from green to brown to camouflage himself. He started puffing his neck out to show dominance. I squeezed off a series of shots, and this is the best of the bunch. He quickly retreated to the safety of the vines when I tried to get closer. The detail in the texture of his skin is amazing.
Nikon D700 with Nikkor 70-300mm VR lens @ 300mm and f/5.6 - Aperture Priority Mode - ISO 400 - 1/400th sec. - post processed in Lightroom 4.1 and Topaz.
I just recently (last week) received my new D700, and I am just blown away with the detail and richness of the pictures.
