darktable + Hugin have me covered for photography. I just want better Wayland support. Specifically I'm waiting for Wayland to get color management merged--even if it only supports standard definition and old ICC profile formats as a stop-gap.
And with respect to color management and Wayland with the rumored next release of nvidia drivers potentially supporting Wayland that's about the only thing that would stop me from switching on all my machines. I know there is an open issue for working on that in both the Wayland official protocols and wl-roots so hopefully soon.
