Yes it depends on the camera and how it is setup. On a higher end camera like a DLSR the user can take control of all of these settings. For example manually setting the cameras ISO setting should lock down the CCD bias voltage and also the amplifier gain and of course manual control of exposure will lock down the aperture and shutter speed. On many consumer grade cameras users can not take control these things. ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
