Auto Correction of Brightness and Contrast (Auto
Lighting Optimizer)
Still Images Movies
Correct brightness and contrast automatically to avoid images that are too
dark or have too little or too much contrast.
● On the Quick Control screen (
=
23),
choose [ ], and then choose the desired
option.
● This feature may increase noise under some shooting conditions.
● If Auto Lighting Optimizer makes images too bright, set it to [
]
or [
].
● Images may still be bright or the effect of exposure compensation
may be weak under a setting other than [
] if you use a
darker setting for exposure compensation or ash exposure
compensation. For shots at your specied brightness, set this
feature to [
].
Changing the ISO Speed
Still Images Movies
Set the ISO speed to [AUTO] for automatic adjustment to suit the shooting
mode and conditions. Otherwise, set a higher ISO speed for higher
sensitivity, or a lower value for lower sensitivity.
● On the Quick Control screen (
=
23),
choose [ ], and then choose the desired
option.
● Although choosing a lower ISO speed may reduce image
graininess, there may be a greater risk of subject and camera
shake in some shooting conditions.
● Choosing a higher ISO speed will increase shutter speed, which
may reduce subject and camera shake and increase the ash
range. However, shots may look grainy.
