Similar to Hidden Faces, but applying it to everything... you can see a rabbit in the clouds, Jesus in your toast, inappropriate things in apricots, an old man in a rock, etc. And make it be an "accidental" sighting, i.e. don't set up a banana and oranges, though taking an object that already looks like something else and putting it in a studio setting would be okay.
Since a lot of us shoehorn things because they look like the subject of the challenge (the "Masks" challenge comes to mind, as do a certain entries with an RV), let's make this type of "shoehorning" the actual challenge.
PS: Yes, I know it probably has been suggested before, but I woke up thinking about it so I couldn't resist |
