Cautions for < F > Handheld Night Scene
z In flash photography, if the subject is too close to the camera, the picture may
come out extremely bright (overexposure).
z In flash photography, if you shoot a night scene with limited lights, the shots
may not align correctly. This may result in a blurry picture.
z In flash photography, if the human subject is close to the background that is
also illuminated by the flash, the shots may not align correctly. This may result
in a blurry picture. Unnatural shadows and unsuitable colors may also appear.
z Flash coverage angle with an external Speedlite:
- When using a Speedlite with automatic flash coverage setting, the zoom
position will be fixed to the wide (wide-angle) end regardless of the lens’s
zoom position.
- When using a Speedlite requiring manual flash coverage setting, set the
flash head to the normal position.
Cautions for < G > HDR Backlight Control
z The image may not be rendered with a smooth gradation and may look
irregular or have significant noise.
z HDR Backlight Control may not be effective for excessively backlit scenes or
extremely high-contrast scenes.
z 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.
