Hi, there is in dt an hidden IOP named gamma.c that is the last one in the pixelpipe. Looking at the code, it is useful to display the masks and convert the pixels to uint8 values.
However, it does a gamma conversion too, with a linear and gamma parameters. First of all, this conversion seems damaging in a calibrated and linear workflow because it (seems to) prevents the color picker to get accurate pixel values readings. Then, I don't see where the gamma and linear parameters are grabbed. Could anyone tell me what it does and how ? Having an arbitrary gamma conversion there could be redundant with the display gamma and is a serious matter for color management. Thanks, Aurélien. ___________________________________________________________________________ darktable developer mailing list to unsubscribe send a mail to darktable-dev+unsubscr...@lists.darktable.org
