Re: [APML] Calculating background colour drift

[Matt BenDaniel <matt@starmatt.com>]

Nicola,

My opinion is that such an exercise, although perhaps interesting, would not help produce more aesthetic results. I think that in the end there is no substitute for the eye of the person doing the image processing. There is very wide latitude for color balance. There is no "correct" control to which our results can be compared. The best we have is a "median" result of many astrophotographers' work. Astrophotography is art not science. You must have an intuitive sense in your mind's eye of what you want to produce.

The color tint of the film base is implicitly corrected during the process of curving the image. No thought is really needed.
