G Shooting Backlit Scenes
When shooting a scene having both bright and dark areas, use the
<G> (HDR Backlight Control) mode. When you take a picture, three
continuous shots are taken at different exposures, and the resulting
image with the least loss of shadow detail due to backlighting and
widest tonal range is recorded.
Shooting Tips
Hold the camera firmly.
While shooting, hold the camera firmly and steadily. If any of the
three shots are greatly misaligned due to camera shake, etc., they
may not align properly in the final image.
Even if a Speedlite is attached to the camera, it will not fire.
See the cautions on page 74.
HDR stands for High Dynamic Range.
