Matthias, regarding workflow - I am testing/learning LIghtroom 3 beta and am trying to get an organized photo development system going. And I'm trying to wrap my brain around all of the elements and options to establish how I can optimize my workflow.
So there are the various file formats (DNG, RAW, XCF), and the applications (GIMP, Lightroom, UFRaw). Now, in a previous posting I was also struggling with this similar issue which you helped me with, and maybe I should have tacked this on to that conversation...But here are my thoughts, and hurdles regarding this: I would like to use LR for organization, image management and for most of my image processing and GIMP for my works of art. But LR has some slick, powerful and advanced tools, that seem to rival those of UFRaw.
The trouble I"m having is with the file formats and which to use and when. For instance, I"m working on a photo in LR and realize I need to remove someone's head or foot, and want to do that in GIMP. Should I export it as a DNG (or TIF) file, then use UFRaw (only - since LR seems to perform the like changes as UFRaw) to export it as a sRGB file for GIMP? Then once I'm done with GIMP, export it as a XCF file and as a JPEG for the internet?
Can you feel my pain?
I appreciate your patience and expert advise.
