Corky’s deer were watching me through the fence. The camera flash reflected from their eyes. I lightened the image so that you could see the faint outlines of their bodies. I could not see them, and they knew it. Dunno how they know when I can see, and when I can’t. Still, that bit of knowledge allowed me to take a picture of the group. They didn’t scatter because they assumed (assumptions are never a good idea) that as a visual predator rather than a nose predator, I didn’t know where they were. Fooled ’em.
