z Auto Correction of Brightness and Contrast
(Auto Lighting Optimizer)
z
This feature may increase image noise under some shooting
conditions.
z
When the effect of Auto Lighting Optimizer is too strong and images
become too bright, set it to [
] or [ ].
z
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 flash exposure compensation. For shots at
your specified brightness, set this feature to [
].
z
Fewer continuous shots may be available when this setting is set to [ ].
z
Capturing Natural Colors (White Balance)
z
Any correction level you set is retained even if you change the white
balance option.
z
On the advanced settings screen for correction, B is for blue, A for
amber, M for magenta, and G for green.
z
One level of blue/amber correction is equivalent to about 5 mireds on
a color temperature conversion filter. (Mired: Color temperature unit
representing color temperature conversion filter density)

Custom White Balance
z
Capturing a white subject that is too bright or dark may prevent you
from setting the white balance correctly.
z
Choose [Cancel] to choose a different image. Choose [OK] to use that
image for loading white data, but note that it may not produce a suitable
white balance.
z
Instead of a white object, a gray chart or 18% gray reflector
(commercially available) can produce a more accurate white balance.
z
The current white balance and related settings are disregarded when
you capture a white subject.
