do the eyes have a shutter speed?
I was thinking, since a camera can match the shutter speed of a helicopter blade, or something really fast, to make it look like its not spinning, when its really spinning very fast, I thought "Huh, do they eyes have a shutter speed like a camera?" Maybe this is a dumb question, but I'll ask anyway. Cheers!
