And then trash NX-D
I was working with NX-D from 2018-2019, converted 12.000 photos, before switching to RawThwerapee. If you would like to have real accurate colors, forget NX-D! It uses some hidden internal adjustments, which you can’t reproduce or retrace with other software.
Please set up a proper color management, with correct and fitting profiles (no chance with NX-D), and keep going with RawTherapee.
