Perspective helps to create the illusion of reality by locating forms in space according to certain conventions. In most painting perspective doesn't have to be precisely correct, as long as it looks right. Your understanding of nature and correct observation make the difference between an awkward drawing and one that is convincing. Here are some tips and basic definitions to get you started:
- Linear perspective
- horizon line: the artist's eye level
- station point: where the artist is standing
- picture plane: imaginary vertical surface through which artist views the scene, parallel to the art support (like looking through a window)
- cone of vision: limits of vision beyond which distortion occurs (90 degrees--45 degrees to each side of the artist); similar to wide-angle distortion with a camera lens
- vanishing point: a point at which parallel lines appear to converge.
- Aerial perspective
- also called atmospheric perspective
- suggests distance through soft edges, light values, cool color
- suggests nearness through darker values, warm color, texture, crisp edges
- utilizes sharper detail in the foreground
- Other means of suggesting distance
- overlapping objects
- converging lines
- diminishing sizes
- gradation of values and colors
- light and shadow (also important to showing 3-dimensional form)
