Have you ever taken a photo of something only to look at it later and realize that something else was in the photo that you didn't notice was there originally? I didn't even see the spider when I took this shot. I was attracted to the plant growing on the rock.
Yes, that happens to me, too. I have often taken a picture of rock for the texture and location shots, and discover a face in the rocks after I get it up on my computer. If you're interested in some examples, check out my "Faces of Nature" gallery here: https://www.hockshots.com/Faces-of-Nature/
(Many of these were photographed because of the faces that I saw before I took the photo, but quite a few were not.)
