When I was at the Monterey Bay Aquarium I came across this sign (and this octopus) and it made me giggle. I mean he's cute and all, but does he really get flashed that much? I hope not, especially since the aquarium is full of kids.
Don't worry, I didn't use a flash to take this photo. I just set my camera's ISO to 1600, the highest one I have. It turns out that the is similar to the human eye with a light-sensitive retina. And that's why they don't appreciate the flash.
