Ive been trying to make custom camera profile using argyllcms. I've been following these 2 guides.
https://ninedegreesbelow.com/photography/well-behaved-camera-profile.html#step-by-step-procedurehttps://rawtherapee.com/mirror/dcamprof/dcamprof.html#own_targetI'm using argyll to generate the target instead of dcamprof just to simplify the workflow. I played with the arguments until the target 'looks good'. I printed the target out on Red River Baryta Fiber 300 on my ipf8400 using the adobe color print utility. I'm trying to profile my Nikon D610 using a high CRI LED video light as the light source.
Generate target patches and .ti1
targen -v -d3 -G -e4 -B1 -g10 -s8 -f462 -m7 -Q
Generate .tif and .cht
printtarg -v -S -ii1 -r -T 600 -C -p Letter
Photograph target and flat field
Read chart with i1pro to get spectral power distributions
chartread -v -H target
Convert spec to cie
spec2cie -v target.ti3 target.cie
Open raw file in raw therapy, wb off paper white, apply flat field shot, loosely crop target and rotate, export using 'save reference image' in color management tab with wb applied. I took Several shots from +0 to +3, and chose the brightest one.
Read values from raw.tif
scanin -v -p -dipn raw.tif target.cht target.cie
Generate .icc profile
colprof -v -am -u -D"D610_matrix.icc" -O"D610_matrix.icc" raw
colprof -v -ax -u -ql -bn -D"D610_XYZcLUT.icc" -O"D610_D610_XYZcLUT.icc" raw
The matrix based profile is super washed out and the cLUT profile isn't even close. The errors, white and black point of the profile are also off. I've uploaded all the files in the drive folder below.
