HDR Backlight Control Mode
When shooting a scene having both the bright and dark areas, use the [ ] ( 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.
* HDR stands for High Dynamic Range.
Shooting tips
Hold the camera steady.
Keep your elbows close to your body to hold the camera steady ( ). 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.
Caution
Compared to other shooting modes, the image area will be smaller.
RAW image quality cannot be set.
Flash photography is not possible.
Note that the image may not be rendered with a smooth gradation and may look
irregular or have significant noise.
HDR Backlight Control may not be effective for excessively backlit scenes or
extremely high-contrast scenes.
When shooting subjects that are sufficiently bright as they are, for example for
normally lit scenes, the image may look unnatural due to the HDR effect.
If you shoot a moving subject, the subject's movement may leave afterimages or
the surrounding area of the subject may become dark.
The image alignment may not function properly with repetitive patterns (lattice,
stripes, etc.), flat or single-tone images, or images significantly misaligned due to
camera shake.
It takes some time to record images to the card since they are merged after
shooting. “
buSY ” and “ BUSY ” appear in the viewfinder and on the screen,
respectively, as images are processed, and shooting is not possible until
processing is finished.
