     Take and lock your shutter speed at 1/15 then bracket DOWN (smaller
f-stops) from the camera's choices for aperture. I think this may help you
prevent washout of the colors in the brighter areas. You will need to operate
the camera manually.

     You might want to go to a custom lab, and tell them that the first frame
is a greyscale card (available at your local custom printing labs). Tell them
to balance for color on that, then lock the settings for color balance. Most
labs will automatically evaluate the color balance on each frame, based on an
average of what appears in 'most' frames. This is obviously not worth a toot
for screen photos... It's there on the film, and not screwed up in development.
It's the color balance on the photo printer.
