Whoa, the Government of Canada has an incredibly detailed page on the dark art of scanning photographs with a flatbed scanner. It is full of practical & theoretical info, incl. color theory (color space, models, gamuts, accuracy, distance, illuminance, bit depth, dynamic range, etc.), common scanning issues… and you can even the #Coloraid (Wolf Faust) "IT 8.7/2" color calibration target referenced, plus #GIMP screenshots 🤯
A quickie ten minutes #biking ride around Montréal to get some air and reset the mind, after spending two whole days trying to do color calibration for 4 scanners on Linux, a maddeningly tedious and confusing #colormanagement process 😌
I have 3+ #scanners, all with wildly different #color results, as you can see below. At least 2 of them can scan directly over LAN (in Simple Scan).
Ideally I'd want #colormanagement / calibration of scans, ideally with "Simple Scan" (otherwise, how do you do it with XSane?). I have a ColorMunki spectrophotometer, if it helps.
@yantor3d Ah, color. No other area of a vfx pipeline makes you realise that "you know nothing, John Snow."
The more you learn about color science, the more you go "wait, so I've used term X wrong for years?" or "wait, so the DCCs just did it wrong for years and nobody cared or noticed?"
The end state is madness where nothing holds true anymore:
