How to Create Depth
1. Linear Perspective - By using either 1 point perspective, 2 point perspective, or 3 point perspective, an artist can create the illusion of space. Linear perspective is a drawing method that uses lines to draw objects in space.
2. Overlapping - When one object is positioned in front of another object, part of the object behind it may be blocked from view. This is called overlapping.
3. Size - Objects that are closer to a viewer appear larger than objects that are further off in the distance.
4. Placement on the Surface - Generally, objects that are positioned lower on the picture plane will appear closer than objects that are positioned higher on the picture plane.
5. Color and Value - Objects that are closer to a viewer appear darker in value and warmer in color. Objects that are further away appear lighter in value and cooler in color.
6. Detail - Objects that are closer appear more detailed than objects that are further away.
