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.

Exposur

e 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.

NOTE: The color of your object will effect the brightness of your subject

and the selection of your ISO or EV may be effected. Check you camera

instructions for more information about ISO and EV
