Don Yes I tried this many years ago with three pictures taken with film camera on a tripod, scanned them and couldn't get the results in PS (5.0) that I got thru the double or triple exposure in the camera thru different color filters.

Anything that moved, e.g. clouds, water, would have natural colors except where the image changed and that change would register in the color of the filter at the time of exposure. This may be what Emily was referring to. Has anyone tried 3 exposures through 3 filters on digital and then overlaid in PS? Or how about just 3 exposures and then pulling out a separate channel for each and overlaying those? Does that make sense? Don
