ISO setting verses exposure compensation - Kodak C330

My Kodak C330 has an adjusment for exposure compensation and another
for manually selecting ISO 80-400. The manual says that both affect
picture brightness, so what's the difference between the two?

 

Exposure compensation: If the camera automatically selects the lens
aperture and shutter speed, you may want, in some situations, to
increase or decrease the brightness of the image. If the latter, for
instance, then if you use + exposure compensation the camera will
increase the exposure settings above and beyond what it would otherwise
have used. So you are directly affecting picture brightness in your
selection of + or - exposure compensation.

ISO: This is basically setting the gain on the sensor. So for a given
lens aperture and shutter speed, if you increase the ISO the sensor is
more sensitive and the picture will be brighter. This comes at the
expense of additional noise as the noise gets amplified also.

 

Above is correct. You are changing the exposure settings away from what the
Camera indicates.

Below is true, but it is unlikely that the OP will be using Manual Settings,
and the extra brightness will not happen in any Auto Mode.

Changing the ISO setting will make the Camera more or less sensitive to
light. However the Camera Automation will then use a different Exposure
Value (Shutter speed - aperture setting) from what it would have done at the
previous ISO. The bright areas of the picture will mostly be just as bright
as they would have been.

However raising the ISO figure will allow the camera to work within a hand
holdable Shutter Speed Range, when a lower ISO would have meant it being
below this speed.

I too have a Kodak c330.
It's a fine little camera.
Leave the ISO set at 80 or Auto; forget ISO400
in the dark as the pics look horrible.

I like to use the 2sec timer for stationary objects as it reduces shake
when you press the shutter.
