Hi Elle!
This looks like a great project to me.
"I use linux. This code, as is, won't compile under windows."
Then it won't under MacOSX either, I assume?
In case it will anyway, and in case I will be able to do my part:
Under 0.3.1 GOALS: you write
"(1) Un-Dng dcraw, That is, replace the Dng-derived camera coefficients with
camera coefficients derived from Argyllcms colprof matrix profiles"
Is it restricted to *matrix* profiles? I get much lower dE values with LUT
profiles.
In any case, your text is already working on me with goal (2): "Gain a better
understanding of what dcraw does when it renders a raw file."
Best regards - Hening.
