Sealife DIGITAL FLASH manual Depth Visibility Light

Page 29

You notice the deeper you go, the lower the visibility. The darker the light conditions are, the higher the ISO. This makes your camera more sensitive to light and will serve to compensate for the absorption of light at depth.

Exposure Value (EV) also allows you to increase, or decrease, the camera’s light sensitivity. Increase EV to brighten images, and decrease EV to darken pictures. You may choose to increase the EV setting depending on depth, visibility or ambient light.
