What light level can take a silhouette effect?

Silhouette effect can be achieved by using backlight level.

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.

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.

Specific method: 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.
