In every perspective rendering you create, you determine the viewer's eye level by choosing the position of the horizon line. You control whether you want viewers to feel like they're looking at the objects in your rendering from above, below, or straight on. For this reason, always begin a perspective rendering by making sure your horizon line is parallel to the top and bottom of your rendering space.
If you want viewers of your rendering to feel like they are.
- Looking downward: Place the subject below the horizon line.
- Looking upward: Place your subject above the horizon line.
- Looking straight on: Place your subject so that they touch or cross over the horizon line.
Sometimes referred to as your eye-level line, the horizon line is an imaginary line that divides earth from sky. The horizon line is exactly at the level of your eyes as you look straight ahead.
