Don’t Ignore the Empty Spaces
One of the most useful ideas when solving visual puzzles is to pay attention to empty space.
Most people naturally focus on the objects that are actually drawn. We notice the people, trees, and other visible elements while treating the spaces between them as unimportant.
In an optical puzzle, that can be a mistake.
Sometimes the outline of a hidden object is created partly by the objects themselves and partly by the empty areas surrounding them. The shape you’re searching for may become visible only when you stop concentrating on the individual objects.
Look between branches. Examine the spaces around the people. Notice unusual gaps and outlines.
You may find that an apparently meaningless space starts to resemble something familiar.
Try Changing Your Viewing Distance
Another useful trick is to change how far away you are from the image.
Look at it closely for a few seconds and then move farther away. When you do this, individual details become less dominant and the overall shape of the illustration becomes easier to see.
Sometimes a hidden figure is difficult to recognize when you’re looking at every small detail separately. When you step back, several shapes can visually combine into one larger form.
You can also slightly change the angle at which you’re looking at the picture. Even a small adjustment can sometimes make an unusual shape easier to recognize.
