Description

This is a test run. An attempt at portraiture. I will have to wait until next season to acquire adequate data. The later versions are LLRGB composites. Extract L R G B channels with ImageMagick and recombine in StarTools LRGB. Provides greater control over saturation and chromatics in the Color module.
