I use a lot of still images in my video work, one of the things I try to do is to keep post production on my photos limited to effects that I can easily replicate in final cut on my video clips so I can easily match the videos to the stills… final cut has some layer modes and blend modes that work the same way as photoshop…
I am just beginning to lear cs6 and premier so I can not give you specifics here, but there is a photo technique that maybe if you can figure out how to replicate it in your nle might help you out..
here is a link to an article that has a simplified version of a photoshop technique I sometimes use to bring up shadow details for contrasty images for magazine reproduction…
hope it helps you figure out a solution..
