Re: [Gimp-developer] Darktable plug-in in GIMP

Hi Mika!

you might want to have a look to the PhotoFlow plug-in as well, which tries to provide the same sort of 
Photoshop/Lightroom integration in the GIMP world.
It is designed in such a way that you can re-process the original RAW file from the saved XCF by simply 
re-running the plug-in on the layer that was created by the initial RAW loading.

If you have access to youtube, here is a 15mn video that shows how all this works in practice:

From the RAW processing point of view, PhotoFlow is almost as feature-rich as Darktable, and has even some 
advantages like LMMSE demosaicing and inputs NR for high-ISO images.
