It takes a hell of a good digital camera to do the kind of things film cameras did routinely.
One example: Astronomical photos in digital can use something called "long exposure noise reduction."
This takes twice as long to take a shot because the camera takes the long exposure, then closes the shutter and repeats the exposure so it can electronically subtract the thermal signature of the camera.
Needless to say, you don't find this kind of thing on your typical point-and-shoot.
Even then, expert night-sky photographers take multiple images and calibrate them externally. Way over my head.
