This Week Is All About Color
I've been working on a Lab Color Reference Chart, which you can download here. I looked through many thousands of images to find examples of common colors. After sampling and sanity checks on the data, I came up with these numbers as starting points for white balance and color correction in general.
These references are already quite valuable in my work; I hope they help you also. I put a copy of the png file in the directory I'm working in, to give me quick reference to the chart while working in Darktable.
The RAW file used in this video is available here. Thank you Andreas for the contribution 🙂
I also calibrated my monitor for both web and print profiles. After a bunch of bumping around in the dark, I came up with a simple solution here:
#!/bin/zsh dispwin -c dispcal -v -m -H -y l -q l -t 6500 -b 80 -g 2.2 web targen -v -d 3 -G -f 128 web dispread -v -N -H -y l -k web.cal web colprof -v -D "web" -C "Harry Durgin Photography" -q m -a G -n c web dispwin -c dispcal -v -m -H -y l -q l -t 5500 -b 80 -g 2.2 print targen -v -d 3 -G -f 128 print dispread -v -N -H -y l -k print.cal print colprof -v -D "print" -C "Harry Durgin Photography" -q m -a G -n c print
I switch between them with a hot key sequence. For web I use
dispwin -I web.icc
and for print
dispwin -I print.icc
I hope it works for you too.
