Law of photographic perspective

Photography, like painting, must create an effect similar to the real three-dimensional space on the plane of two-dimensional space, and must make use of the law of spatial sense produced by the fixed psychology formed by human experience. This law of spatial sense is what we usually call it? Perspective? . Let me introduce you to the perspective of photography, hoping to help you!

(1) Perspective Law of Photography: Body Perspective

Body fluoroscopy is also called. Geometric perspective? And then what? X-ray? , based on the principles of optics and mathematics, draws objects with lines on the plane to obtain three-dimensional visual effects. It includes three aspects: First, the represented object shrinks in a certain proportion with the increase of distance. Secondly, when people observe objects, where are their eyes? Opinion? Invisible, the viewpoint extends forward? Line? Call? Sight? The one corresponding to the distant viewpoint? Point? Call? Disappear? . No matter what volume of the object is distributed in space, it will take the line of sight as the central axis, and the extension line of its contour will gradually shrink with the increase of space, and finally concentrate on the vanishing point. Finally, due to the different angles between the line of sight and the object, the perspective state and direction appearing on the screen are also different, giving people different sense of space.

Normal perspective (also known as head-up view) gives people a sense of space when standing and observing things at ordinary times.

Frog perspective (also called looking up) Frog perspective gives people a sense of space when looking up at the scenery.

Bird's-eye perspective (also called bird's-eye perspective) gives people a sense of space when observing things from above.

(2) The perspective rule of photography: aerial perspective.

Air perspective is also called tone perspective, tone perspective. Because the air is full of media that can diffuse light, in human visual perception, the contrast between light and shade is large, the outline is clear and the color saturation is large. With the increase of spatial distance, the contrast between light and dark of the object decreases correspondingly, and the outline becomes blurred, but the brightness increases. This change of visual perception can be summarized as (from near to far): object image: clear ~ soft ~ hazy tone: deep thick ~ light ~ bright color: warm tone ~ neutral ~ cold tone, which is the law of air perspective.
