What does shadow highlight mean in photography?

In photography, shadows refer to places that are still dark after exposure, and highlights refer to the overexposed parts of photos.

After photography is completed, the image information stored in the medium must be read by human eyes again through conversion. The specific method depends on the photosensitive means and medium characteristics. For film cameras, there will be chemical processes such as fixing, developing and enlarging. For digital cameras, pictures need to be processed by computers and then output by other electronic devices.

Techniques for solving exposure problems in photography;

1, highlight the picture

When taking pictures with high light tone, you need to increase the exposure. Because of shooting a high-light tone picture, the camera's automatic exposure system will think that the picture is too bright and automatically reduce the exposure value, which is very common when shooting a snow scene.

Step 2 highlight the picture

When taking pictures with high light tone, you need to increase the exposure. Because shooting a picture with high light tone, the camera's automatic exposure system will think that the picture is too bright and automatically reduce the exposure value. This is very common when shooting snow scenes.

Step 3 spot metering

The advantage of spot metering is "accuracy". Spot metering is most suitable for shooting in the environment with complex light and large light difference ratio, which can accurately control the exposure of the picture. Center key metering is not as convenient as average metering, and it is an excessive state of average metering and spot metering.
