Active D-Lighting (P, S, A, and M Modes Only)
Active D-Lighting preserves details in highlights and shadows,
creating photographs with natural contrast. Use for high
contrast scenes, for example when photographing brightly lit
outdoor scenery through a door or window or taking pictures of
shaded subjects on a sunny day. It is most effective when used
with matrix metering (
