What light position can be used to shoot a silhouette effect?

Use backlighting to create a silhouette effect.

Backlighting is a situation where the subject is exactly between the light source and the camera. This situation can easily result in the subject being underexposed.

Under normal circumstances, photographers should try to avoid shooting objects under backlight conditions, but sometimes the special effects produced by backlighting can be regarded as an artistic photography technique.

Although backlight conditions increase the difficulty of photography, backlight conditions can sometimes be used in certain artistic creations. Skilled photographers often use backlighting to achieve some unusual visual effects. For example, backlighting is particularly good at showing the outline of an object sharply and vividly. Specific method:

Since the subject is exactly between the light source and the camera, the background brightness is much higher than that of the subject. Since the background occupies a larger area in the picture than the subject, the automatic exposure detection program of the point-and-shoot camera will instruct the camera to expose according to the light conditions of the background, causing the subject to be underexposed and resulting in failure of photography.

Backlight conditions greatly increase the difficulty of automatic exposure for point-and-shoot cameras, so in general photographers should try to avoid shooting objects under backlight conditions.

However, there are still some ways to avoid photography failure under backlight conditions. If the subject is not far from the camera, the photographer usually turns on the flash to increase the brightness of the subject; if the distance between the subject and the camera exceeds the effective range of the flash, a double exposure method can be used.
