How to use Active D-Lighting
This is a way of balancing up high-contrast scenes in-camera using exposure and processing together
You can choose the strength of the D-Lighting setting manually, or select the Auto option if you’re not sure how much compensation is needed. The higher settings are good for very high-contrast scenes, but the results can look unnatural.
Bracketing options
To compare an uncorrected shot and one with Active D-Lighting applied, use the bracketing feature in the Custom Setting menu. Look for the Bracketing/flash option and change the Auto bracketing set from AE bracketing to ADL bracketing.
