Unlike film, you can'y simply open the shutter and integrate the
image over time arbitrarily. CCDs are extremely noisy; silver
nitrate (etc) it's at atomic scale.
Hi
Actually, once compensated, CCD's have much more
dynamic range than film. They can be used to integrate
over long periods of time ( usually cooled ). They
have issues but don't confuse poorly compensated
camera's with the ability of a CCD.
