I always recommend RawTherapee for serious photography work. In addition to having been (at least originally) written by a complete colour theory geek and featuring a treasure trove of knowledge in the form of its companion RawPedia, it supports a whole host of raw formats, X-Trans RAFs among them (although Foveon X3Fs regrettably still an open issue).
replyI appreciate RawTherapee too and used it for a long time, but I started to notice that it really can’t match DPP for rendering Canon raw images. The denoising is nowhere near as good and it takes a lot of work to make the colors come out as good as DPP which has same processing profiles like “Faithful” that just look great out of the box.
