When I was a kid I used to like the drawings that would contain embedded images. It was fun to find animals in tree branches. Our brains are wired to look for patterns, it is a survival strategy. However sometimes we perceive things that really don’t exist like a bunny in clouds or a water dipper in the stars.
A while back I had an Olympus TG-2 camera which had a variety of “art” filters that were built into the camera. One of these produced mirror images.Mirrored images can be created with Photoshop, but this was a lot easier.
Everytime I look at this photos I see another face or animal. Give it try.
