Color Management.

Converting the RAW CCD data to RGB yields an under- saturated image like this one.


To process the color I convert from RGB to LAB color space. LAB consists of a luminance value (L) and 2 chroma values (A+B). Multiplying A + B with a constant increases color saturation without changing luminance. However I found increasing A and B by the same amount produced bright orange where there should have been red. Changing the two independently seems like a useful start to controlling the colors.

I have something much fancier in might (see my LABwarp {google it} program for a clue as to what is ahead).
