I reached out to Thomas Modes, one of Hugin’s (currently only) developers, to let him know about this place and hopefully to encourage him to make an appearance here. He prefers to use the mailing list as the one centralized place for discussions due to time constraints, though I hope you (Thomas, if you’re reading this) take a chance and check in here.
Thomas mentioned that Hugin now supports using the command-line RawTherapee executable to convert raw files to TIFF. This feature is available in the default branch, and you can help by testing it. Let us know which operating system you used, which version of RawTherapee and Hugin you tested, and how it went.
Currently I am building and packaging the default HUGIN branch from the mercurial repository (Hugin / Hugin / [2b2251]). This should be the good one for getting the latest features, right?
It seems I have fixed both cpfind and rawtherapee invocation. It works on my Ubuntu system. Could you please check again? If it is OK for you as well, I will confirm the fix on launch pad…
