In another of these never ending threads that is the TradeMark of UbuntuForums, I came across a list of all the design, photo, video and animation tools available for Ubuntu Linux. The thread is 114 posts long (as of writing) and the content has been moved to an independent wiki: artlinux.wetpaint.com. The real meat is the top left box – “Navigation”.
While it contains only basic information on the programs and not all are interesting for photography, this is a good starting point if someone needs an overview of “what exists”. And unfortunately, there is no Photoshop or Lightroom Open Source equivalent that had gone unnoticed so far… if you DO find one, though, please let me know 🙂
Still, the link is worth a visit.
