What effect does backlighting usually have?

When shooting people in backlight, the subject is in front of the light source, and the photo will appear to be in great contrast with the environment. Accurate exposure is the key to taking good photos. The background is bright and rich in details, and the subject should not be too dark, but also details. But when the main body is too dark, you can use a reflector or flash to fill the light. Backlight shooting can produce silhouette light, outline the outline of the subject, play a role in separating from the background and further play a role in shaping. Bright lines are formed on the modeling edge of the subject, which can render the atmosphere to be expressed and enrich and activate the picture. Backlight photography has two forms:

One is to make the subject underexposed to form a silhouette effect; The other is ordinary backlight photography. Backlight photography, when measuring the main part, it is best to use spot metering for metering. When shooting in backlight, the subject's back is facing the sun, which will lead to the problem that the subject's face is too dark. This is because most cameras will preset all the framing pictures as the basis for metering. In the backlight environment, the light behind the portrait is already very strong. After the average calculation, the camera will think that the front darkness of the portrait is normal, which is why the backlight environment will shoot a "big black face". How to solve the problem of backlighting people? 1. Adjust the camera flash mode to forced flash mode.

Second, people should be within 3 meters of the camera, not too far away.

Thirdly, if you forget to switch to the forced flash mode and your face is too dark, you can use software to correct it during development. Backlighting is not the same as photographing scenery. Taking photos of backlit people usually points the flash at the face. But the photos taken will make people's faces fill up too obviously. There may even be a tendency to overexpose. We should raise the flash by 45 degrees and pull out the reflector inside to form a refracted flash. So that the light reaches people's faces much softer. There is no need to reduce the flash when the flash fills the light. Another method that will be very effective is to use a reflector to reflect light. Backlight shooting characters can sometimes deliberately not fill the light. At this time, if you increase the exposure, it is generally enough to add two or three files.
