please is there some way to automatically export reference images for profiling from RawTherapee, ideally with a commandline? We’ll have tenths of those raw photos and clearly don’t want to export one after another manually.
– even a keyboard shortcut for this button would help, I would use AutoIT to do this.
– it is quite easy to synthesize PP3 files and then execute processing from a commandline, but I have no clue if there is a way to e.g. set defaults incl gamma=1.0 in .PP3 file to get identical result via normal export of an image to avoid clicking this export button in GUI manually.
Any help greatly appreciated! Thanks so much in advance,
Stepan
nono, I worry this doesn’t work. Problem is images for profiling are NOT exported usual way. You use this specific button that completely bypasses any export.
I tested now - this button results in a tiff file written, but I don’t see any pp3 or other file created together with it, unfortunately.
To make a good image for profile, regardless of the quality of the shot (equality of exposure, value of exposure, reflections, etc.). It is indispensable (for me) that White Balance image is good.
Of course, the exposure must be almost perfect, hence the shooting by 0.3d.
In addition you have to work with gamma = 1, and of course without profile
This supposes - an exposure (in term of illuminant) of which we are sure of the good value ??!!
Or what I recommand, to use is “Spot WB”, on a cell which Lab* values (a and b) are very near from zero (pure grey)
Of course I will be told that DCP profiles are less “sensitive” than ICC, but if we want a good result…
