@paperdigits thanks, I checked for this. I have the /in folder but not the /out. Though I have 11 choices for export profile in the dt dropdown.
@davidvj, yes sRGB but there are a number of sRGB profiles. For example rawtherapee ships with V2 and V4 profiles which are slightly different. And it seems some have a LUT and others don’t. And I think the number of interpolation points can vary. I think it’s nice to have perceptual sRGB available, hence I thought I’d try other profiles in dt, and/or someone will say why it’s not working at present for me.
