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.
