Shooting Backlit Scenes
When shooting a scene having both the bright and dark areas, use the
< G > (HDR Backlight Control) mode. When you take one picture in this
mode, three consecutive shots are taken at different exposures. This results
in one image, with a wide tonal range, that has minimized the clipped
shadows caused by backlighting.
Shooting Tips
z Hold the camera firmly.
During shooting, hold the camera firmly and steadily. In this mode, three
shots are aligned and merged into a single image. However, if there is
significant misalignment in any of the three shots due to camera shake,
they may not align properly in the final image.
z Compared to other shooting modes, the shooting range will be smaller.
z Although flash photography is not possible, raising the flash beforehand is
recommended, to enable firing of the AF-assist beam ( = 167).
