It&#x27;s an open source tool.  If you&#x27;d like support to be added for your camera, take a look at this page:<p><a href="https:&#x2F;&#x2F;www.darktable.org&#x2F;2012&#x2F;10&#x2F;whats-involved-with-adding-support-for-new-cameras&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.darktable.org&#x2F;2012&#x2F;10&#x2F;whats-involved-with-adding...</a><p>The lens correction comes from the lensfun project, which is also open source.  They even run a lens calibration service if you submit the necessary images:<p><a href="http:&#x2F;&#x2F;lensfun.sourceforge.net&#x2F;" rel="nofollow">http:&#x2F;&#x2F;lensfun.sourceforge.net&#x2F;</a><p>A lot of distributions have ancient versions of lensfun for some reason, so upgrading can make a big difference.  They&#x27;re currently working on splitting the lens definition file into a separate package from the software so that it can be updated more frequently.<p>If you have any questions for the developers you can always jump on to #darktable on freenode IRC.  darktable 2.0 has just entered feature freeze.
