is your footage getting darker as you zoom in? The best way is to probably hand keyframe the exposure effect, or a combination of the levels, Hue/Sat or curves, whichever is getting the best result... Synthetic aperture make a grading plugin for after effects called colour finesse is that what you're talking about? I don't think you can animate any of the settings in this short of animating the opacity with it on a adjustment layer. Probably not suitable for what you need to do.
To combat the grain from brightening underexposed footage you can use a degrain plugin (neat video is the best). But underexposed DSLR footage often clips the dark areas and you get big ugly boxy solid black areas, in which case re-shoot!
hope that helps
