This technique relies heavily on what artists call negative space — the apparently empty areas surrounding the main subjects.
Your brain normally treats those spaces as background and largely ignores them.
But the moment you begin examining the background as carefully as the foreground, an entirely different picture can emerge.
Still can’t see the pig?
Try stepping slightly farther away from the image.
Sometimes concentrating too intensely on individual lines makes the hidden figure even harder to recognize.
You can also briefly look away and then return to the picture.
Another useful trick is to change your viewing angle or mentally separate the trees from the picnic scene.
Instead of asking yourself, “Where did the artist draw a pig?” ask a different question:
“Which shapes could become a pig?”
That subtle change in thinking may be exactly what you need.
