[ptx] high colorimetry, auto-luminance for stop-motion work

[Jake Kauth]

Hello all!

My friend Mark is starting a stop-motion animation project, and we
talked several minutes yesterday about the problems he will face.

He plans to use a high-resolution digital camera to capture the
stills for the animation, but one of the problems is frame-to-frame
luminance.  Even with infinitesimal color or brightness variance,
a "throbbing" or pulsing effect will appear if the individual frames
are not color-corrected.

I remember reading something like this on the list, but I don't recall
exactly when... so my question is this:  could Panotools & friends be
used to do micro-adjustments of luminance to force many frames to
match a reference frame baseline?  Any suggestions on technique or 
pipeline?

Secondly, Mark would love to shoot the stop-motion shots with multiple
exposure brackets, and recombine them into one single image with very 
high
color ranges.  The idea is to get more of the color richness of analog 
film
without the terrible turn-around time.

Thanks for your advise!
