I know it's in Affinity Photo. But it's like$50. Adobe PDF CS2 is free now though from Adobe's site. Google it to find out how to get it. Also, if you want, do all your adjustment layers & etc and save it as a PSD. If you want to send it to me I know Affinity will import PSD & could try to then export the adjustments as a LUT for you and send it back. Not saying it'll work but worth a shot.
