I am trying to apply black and white film simulation to a colour image with the gmic command line tool, but the result is a redscale image (for lack of a better word). I assume this has something to do with channels and image formats. E.g:
gmic sample tiger map_clut fuji_neopan_acros_100
I am new to gmic, and there is probably a simple explanation, but I’ve searched through all the documentation and don’t know what’s causing this.
