This baby lizard scampered off a wall at The Garden and onto the dirt when I got too close, then he froze. I slowly moved in closer, shooting the whole time. My camera was about 6 inches from him at one point and he still wasn't moving, staring straight ahead. So I slowly reached my other hand out toward him and he turned his head for a moment, then became unfrozen in a flash. LOL
I had to play a lot with processing in Picasa because he blended in to the ground so well.
