I could help, but I do not know much about cameras. I do know how to depict which picture I like best based on, quality, clarity, angle, theme (if there is one), cham appearance, and the contrasting of all the colors in the photo.
Also, I am a little biased. I noticed last month that I tend to not vote for panther chameleons. This might be because I like the other chams I've voted for more then I like panthers, or because I think panthers get too much credit. But you should know that about me in order to make a better decision on if I would be a good or not.
