illumination with a single strobe more useful than a profile made from
an exposure
averaging 2, 3, or 4 strobes, if that's what you typically use?
When I light my target to make a profile my target must be lit
perfectly evenly, as well the light falling on the target must be the
same color across the target. The only way I know to do this is with
one light since every light is a different color temp. Remember the
profile is fingerprinting your camera, not your lights.
Gray balancing will take care of lighting differences as long as your
lights are close to each other in color temp. The closer your lights
are to each other, the closer your files will be to matching your
subject or product. In practice my strobes are often different color
temps, which I control by measuring each one before I shoot the final
image. I then hang gel strips over heads to reach the same color temp.
It really doesn't matter what the color temp is, gray balancing will
make neutral. I try to keep my lights within 100 degrees when shooting
digital, with film could get away with 300 degrees. We still color
edit every shot, it's just a lot quicker using a good profile which I
get with ColorEyes.
