is pre-programmed to automatically select the optimal ISO value for
underwater flash pictures.
For non-SeaLife cameras, select a lower ISO, like 50 or 100, because
the picture will be sharper and less grainy.
EV Compensation
Your camera's EV (Exposure Value) Compensation setting works very
much like the ISO setting - Increase EV value to brighten images, and
decrease EV value to darken pictures. Just like ISO, higher EV values
will result in more grainy pictures.
For SeaLife cameras, set the camera to Ext Flash mode (or Ext Flash
Auto mode) and leave the EV Compensation at "0". Your SeaLife
camera is pre-programmed to automatically select the optimal EV
value for underwater flash pictures.
For non-SeaLife cameras, start with an EV value setting of -2 and
make adjustments as necessary to achieve the best results. Avoid using
+ EV values.
White Balance
The camera's White balance setting will match your camera's image
sensor to the color "temperature" of the primary light source.
For SeaLife cameras, set the camera to Ext Flash mode and leave the
White Balance on Auto. Your SeaLife camera is pre-programmed to
match the color temperature of the flash.
For non-SeaLife cameras, it is recommended to select the DAYLIGHT
White Balance setting.
