Illusion of Space

             Illusion of space is the way that we look at things, how things seem to be closer and also farther away.  Making an object larger also makes it appear closer, and when an objet is smaller it appears to be farther away.   When an object overlaps another object it makes the object behind it further away by showing that it is behind the other object.  Another way to show Illusion of space is to use color contrasts to show depth.  When doing this you have sharp colors for the objects that appear close, and lighter less distinct colors for the objects that are far away, so they almost blend into the background.
        
            Converging lines is another way to show Illusion of space.  This is where all the lines seem to end at the same point, making the lines larger at the front of the page and gradually getting smaller the farther that they go.

         You can also show Illusion of space by a Two-point perspective.  This is what architects so which creates a more 3 dimensional look too a building.  they do this by taking the picture from the side, on the corner of a building, and not just from the front.
