Interposition is when one object overlaps with another object, and the object being covered is perceived as being farther away. This is one of the monocular cues. This along with texture gradient, linear perspective, aerial perspective, and relative size allow us to perceive depth in pictures and everyday life. This is something that is used by many artists in their paintings. I have numerous personal experiences with interposition in my everyday life.

I experience interposition all the time everyday just like everyone else. When walking to class I see many students ahead of me. Most of the time students end up partially obscuring my vision of other students. The students that are obscured from my view by the other students overlapping them in my vision appear to be farther away. Actually as I write this I am witnessing an example of interposition. I have a “Lucky Charms” cereal cup sitting in front of a bottle of milk. The two objects are overlapping each other in my vision. The bottle of milk appears farther away since part of it is being blocked from my view by the cereal cup.

Interposition is easily one of the most common monocular cues. It is present everywhere. From walking down the street to having cereal and milk. No matter where you look you will see an example of interposition. Artist also use interposition to make objects in their art appear farther away than other objects in the picture/painting. The use of interposition in art makes up view the object in front as being closer and the object behind it as being farther away. An example of this would be if an artist painted a picture where an orange was sitting in front of an apple. To present the apple as farther away the artist will paint the orange covering up part of the apple hereby making the orange seems closer to the viewer while the apple appears farther away. Without interposition our minds would not think and function the same and the world as we know it could appear completely different.
