So - what's the best that can be done with this flawed
data?
In this situation you need to calibrate vignetting and camera response
separately - then only optimise exposure and white balance in a project where
shadows move around.
I'm not sure how that would work; the "vignette" (AKA non uniform lighting) is
much larger
than a single image. Surely vignette calibration applies to (correct) a single
image?
