WB (White Balance)
The white balance setting adjusts the color temperature of the ambient lighting conditions you are shooting
in, so natural colors can be restored. For example, shooting a white object underwater [without photo-
video lighting], will appear blue/green rather than white. Adjusting the white balance setting can offset this
color shift effect and make this object appear white again.
The default WB setting is Auto, which works well in most ambient lighting environments and when using a
photo-video light and/or the included color-correction filter. You may manually adjust the WB color temp
from 3000K (kelvin) to 8000K to achieve the desired color effect. When a manual WB value is selected,
the color effect can be fine-tuned using the Tint adjustments described below.
SeaLife is testing different manual WB and Tint settings in varying underwater lighting conditions and
depths and will post recommended settings to sealife-cameras.com when available.
For best underwater colors, use an underwater photo-video light with at least 2000 lumens. More lumens
are better. Set the WB to Auto when using a photo-video light. You may also use the included underwater
color-correction filter in combination with the photo-video light to further enhance colors.
Tint
The Tint setting is only available when a manual WB setting is selected. You cannot adjust tint if WB is set
to Auto. Tint allows you to fine-tune the manual WB color setting. The tint color scale ranges from -150
(green/yellow) to +150 (magenta) in 10-step increments. Using positive (+) values is more suitable for
underwater.
