Not sure if I have seen this mentioned on these forums but I thought people might be interested in this: From website.. Photivo is a free and open source (GPL3) photo processor. It handles your RAW files as well as your bitmap files (TIFF, JPEG, BMP, PNG and many more) in a non-destructive 16 bit processing pipe with gimp workflow integration and batch mode. .. sounds interesting, only just installed it myself so I can't comment on how well it works. Photivo
It's good place to mention, that Photivo has been landed in my PPA: ppa:dhor/myway (builds for 32/64 lucid/maverick/natty) (sudo add-apt-repository ppa:dhor/myway) Maybe someone finds this repository helpful.
