It is best to use backlight when representing the outline of an object or shooting a transparent and translucent object.

Backlight is a state in which the subject is just between the light source and the camera, which easily leads to underexposure of the subject. Generally speaking, photographers should try to avoid shooting objects in the case of backlight, but sometimes the special effect produced by backlight can also be regarded as an artistic photography technique.

Backlight is light projected from the opposite direction of the camera lens. "Reverse" means opposite to the shooting direction. Include full backlight, side backlight, top backlight and back backlight. Backlighting can hide the structural details of the subject, highlight the outline, better express the sense of depth, form a unique light structure, and produce special artistic effects such as silhouette and glare.

Because the subject is just between the light source and the camera, the background brightness is much higher than the subject. Because the background occupies a larger frame in the picture than the main body, the automatic exposure detection program of the fool camera will order the camera to expose according to the light condition of the background, which will make the main body underexposed and lead to the failure of photography.

Backlight conditions greatly increase the difficulty of automatic exposure of a fool's camera, so generally speaking, photographers should try to avoid shooting objects under backlight conditions.

However, there are still some ways to avoid the failure of taking pictures in backlight. If the subject is not far from the camera, the photographer usually turns on the flash to improve the brightness of the subject; If the distance between the main object and the camera exceeds the effective range of the flash, the second exposure method can be used to shoot.

Although backlight conditions increase the difficulty of photography, backlight conditions can sometimes be used for some artistic creation. Skilled photographers often use backlighting to achieve some unusual visual effects, such as backlighting, especially good at vividly showing the outline of objects.
