HDR Mode
Effects
You can shoot still photos with clipped highlights and shadows reduced for a high dynamic
range of tones even in high-contrast scenes. HDR shooting is effective for landscape and
still-life shots.
With HDR shooting, three images of different exposures (standard exposure,
underexposure, and overexposure) are captured consecutively for each shot and then
merged together automatically. The HDR image is recorded as a JPEG image.
* HDR stands for High Dynamic Range.
