First time seriously getting to use my new 50mm f/2.8...
Not sure what kind of tree frog it was... but made for a good subject. I cropped it down and removed some excess wall and also the pipe clamp he was "sitting" on. Cloned out some scrape marks on the pipe he was attached to. Other than that he already had excellent color. Photo was taken at night and with the flash on my D70 (no external flash). Was real careful to try and make sure it's eyes were in focus.
I have more pics of him... he was a rather patient subject, but this is the only one I got a chance to play with so far.
BTW... Found he sticks to a T-shirt too when he decided I was annoying him and he decided to take a leap of faith off his perch.
