Thanks Jo !
so now I'm working on the OpenCL port. I have this function in the IOP :
#ifdef HAVE_OPENCL int process_cl(struct dt_iop_module_t *self,
dt_dev_pixelpipe_iop_t *piece, cl_mem dev_in, cl_mem dev_out,
const dt_iop_roi_t *const roi_in, const dt_iop_roi_t
*const roi_out) {
heya,

maybe on some systems. the

Hi Aurélien
Fist, thank you for showing me this interesting video.
I just compiled your branch.
My first question is, is it possible to find shift power slope values that
reproduce the result we had before with linear and gamma?
If yes, I think you should compute the new parameters values from
Hi everyone,
when working with color profiles, the main historic issue was the
non-linearity of the sensors/films. Now, it is rather that the color
profile is performed on a chart having 6-7 EV of dynamic range while
modern cameras have 12-15 EV. Simple gamma corrections (invented for CRT
