The only problem that I see with this setup is that it would take a long time
to read numerous shutter speed tests and be somewhat arbitrary. Cool Edit
just doesn't seem to user friendly at such close magnification. When you get
down to the 1/1000sec, ten-thousandths of a second become important. It
could take forever to read a bunch of times in Cool Edit...unless there is a
way to do this automatically that I am unaware of. What would be great is if
there was a way to get this info into a spreadsheet easily.
In regards to the TV/RGB monitor trick, I would think that tapering would
show up on a slide well before the human eye could detect it with this
technique, but I haven't tried it yet.

if someone tells me I'm wrong.
