What's the difference between front light, back light, side light and top light?

1, along the light, the subject receives light evenly, the shadow of the scene is blocked by the scene itself, and the color tone is softer. Can shoot the texture of the object surface, bringing better color reproduction.

2. Backlighting can easily lead to underexposure of the subject, but the technique of backlighting is particularly good at vividly showing the outline of the subject.

3, metering, can produce obvious contrast. It can also create a strong modeling effect.

4, backlight metering, the tone is relatively heavy. The picture has a strong sense of space and rich colors.

5, the top light, easy to cause an abnormal, strange shape. A sense of seriousness and sacredness.

Photometric shooting attention:

(1) Pay attention to the ratio of the light receiving surface to the shadow surface on the screen, and adjust the ratio of the light receiving surface to the shadow surface according to the angle change between the light source projection direction and the camera shooting direction by selecting the shooting point or waiting for the appropriate shooting time. The angle between them is generally 30-60 degrees.

(2) Control the contrast of light, and the light ratio should not be too large, especially when shooting portraits. The light ratio should be 1: 2 or 1: 3. That is, the bright part of a person's face is one or two times smaller than the dark part.

(3) When shooting in sidelight, if the light contrast is large and the background color is messy, you can choose a large aperture and a short depth of field to focus on the subject, so that the focused object is stereoscopic and colorful. Blur scenes outside the depth of field. The color is lighter. By using a long focal length lens and a large aperture, the shape of the characters can be effectively highlighted, and the sense of space and theme can be expressed through the contrast between reality and reality.
