Re: Film vs Digital (double exposures)

Exactly what I had in mind and the effect seems to be the same.  At 
one time I fabricated a device that allowed me to open the shutter 
and then drop a piece of mount board holding the 3 filters, one 
above the other, and take "action" pictures utilizing the same 
technique but with a single exposure.  No reason the same thing 
wouldn't work with digital.  I think the idea came from a Kodak book.

One of the less serious ways that I have used a camera involved taking
a triple exposure through red/green/blue 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?

Yes, actually.  I did this that way:
