Gotta get him a heated blanket to put next to you :)

photopea is not open source ☹️

if affinity had a lightroom competitor i would use that instead. i have affinity photo and its basically on par with photoshop except for edge cases. but yeah as you mentioned not FOSS either.

adobe lightroom and photoshop. no, darktable and gimp are not as good. darktable barely functions with a trackpad and gimp is like photoshop from 2010.
