What does SLR dynamic D light mean?

SLR dynamic D-Lighting is an imaging optimization function of Nikon digital camera. Dynamic D-Lighting can preserve details in highlights and shadows, and create photos with natural contrast for high-contrast scenes. For example, shooting a scene under strong outdoor light through a door or window, or shooting a subject in the shadow of a sunny day.

The metering method depends on the specific shooting scene, and the rule is that the greater the light contrast between the shooting subject and the background, the smaller the metering method;

The use of dynamic D-lighting is generally to take photos with large contrast of light changes in large scenes.

Therefore, it is generally used for global metering, of course, even spot metering can be used, because dynamic D-lighting is a function that reflects the details of light and shade, and is suitable for all metering modes.

Extended data:

Dynamic D-lighting function of SLR: When the brightness of the shot image is dark or the contrast is small, you can use automatic brightness optimization to automatically correct the brightness and contrast. The requirement for image format is JPEG format.

Limit: Generally, it is set to off by default in M and B files, or it can be set to on manually. In multiple exposure, HDR and highlight tone priority modes, automatic brightness optimization will be automatically turned off.

Scope of application: high contrast image, backlight portrait shooting, or loss of dark details caused by underexposure.
