I have been using two compact cameras (sony rx100 iii and a canon ixus 132 hs with CHDK to get raws), but i have this issue where the default RAW white balance in darktable (i guess its a WB issue) are both tinted with pink/magenta, while the jpg doesn’t have that. What is annoying to me is that on my reflex camera i dont have this issue, the WB is ok, so usually i don’t have to deal with that.
same darktable edit but with Color calibration > G > and reduce input B to -0,107 with “normalized channels” checked. but again it may feel a bit greenish while sky is till a bit tinted maybe?
darktable edit with default color calibration, but just changed the temperature from 4271K (plankian, CAT16) to 3884K. I feel its still too blue and still tinted? Maybe i’m wrong? But in that case i feel that its weird that i have to change to WB to match the JPG?
So my question is: is it normal that the white balance doesn’t seem the same as the jpg ? That there is a magenta tint, while no tint in the JPG. And is there an easy way to correct it? Should i be eyeballing the correction with color calibration > G ?
THere is also a tweak that if you calibrate your monitor to D65 and display white and take a picture of the screen, you can use that with the old WB module and use the picker to do an area wb…This can be used as a preset in place of the default reference values used by DT…generally a little less red.
If you have a color checker you can run it through the calibration in the CC module and test the results to see if you get a better delta E by doing so… Aurelian made a video about this…
This assumes that this is an option for you… ie the calibration etc…
There is an issue how dt loads the as-shot white balance. There are some conversions happening in the color calibration module that can create a color cast. As a work-around, I have defined an auto-applied preset for color calibration that will apply it with the setting “as shot in camera”. See issue #9968 in GitHub.
I just tried an experiment. I personally usually use the white balance module rather than the color calibration module for my processing. I just haven’t fully embraced the color calibration module yet. The results of my experiment are here. There is no DT edits applied except the defaults that get applied when you open an image in DT. The top one is White balance set to as shot in camera and no color calibration module. The bottom one is white balance set to camera reference and color calibration set to CAT 16 with as shot by camera for the illuminate. BTW, the image had a magenta cast before setting the illuminate when color calibration was used.
