Darktable, which I&#x27;ve been using for at least three years now, is certainly a reasonable lightroom replacement. Its initially rough edges have been mostly well rounded now, and some of the more hard-line decisions from the developers (like &quot;no file delete functionality at all&quot;) have been sensibly slackened.<p>Some things I think are still missing from open source photography workflow: adequate support Linux from high-end printer manufacturers (eg. I have a Canon Pixma Pro 1 and I basically have to use it through a shitty Windows VM), and better front-ends for lens distortion calculators.
