I took a photo of the new boy the other day and accidentally left the flash on. When the flash went off it appeared that the little fella was temporarally blinded by the flash. I moved my hand towards him and he did not react until I nearly touched him. I had forgotten about it until I read about a snake that was being photographed that was more interested in the flash. It's got me thinking. Snakes don't have eyelids therefore cannot blink. How much damage are we doing to a snakes retina by using flash photography? I don't let people use flash photography around my birds for the same reason. Any thoughts on this subject?
