Im confused on the setting for my camera. Its a kodak v series. It has a iso setting a was wondering what is the point of it. Also should I be setting it at long time exposure or make it normal exposure when taking pics of corals close up.

I DID finally read my manual a coule of months back and it made a diffference in how well i was taking pictures......then the camera got reset somehow and i cant remember where i had everything set at.........

Basically it is a varible that controls the sensors sensitivity to light; the number that you see is the digital ISO equivalent, it translates into the measure of the speed of film.

The higher the ISO, the faster your shutter speed, and still get a bright picture; but the image will be grainy and contain more digital noise. Lower ISO, the longer the shutter speed for the same brightness; but the image will be sharp with very little to no perceivable noise.
