As a starting point for all of my images I establish a 'typical' process for the roll and then batch (style) convert my entire session.
This of course can never be totally satisfactory for all images on the roll but it does give me something that is appreciably better than a Canon jpg by comparison. The 'important' images I then tweak as needed. Removing the base dt conversion and then applying my specific style for 200 images or so takes less than 30 seconds. You may want to give this a shot rather than laboriously processing on a frame by frame basis. David I maintain a series of styles that covers most situations as a convenience.
