I remember about 5 years ago, darktable did have a manual lens correction module. Unfortunately, redmine is down at the moment for some reason so I am unable to check the status of this request. In fact, there is a feature request for a manual lens correction module in the darktable redmine system already (#9087). You aren't the first to ask this question. ![]() This won't prevent me from continuing my move to Darktable, but I feel it's a fundamental flaw in what is otherwise an outstanding RAW development tool. This works well enough, but it adds what I feel are unnecessary steps to what should really be a simple "darkroom requirement".Īm I missing something, or is Darktable missing something? I'm hoping it's the former, but beginning to suspect it may be the latter! The only way I can achieve this right now is to export my image to a TIFF file, load it into GIMP, and use the lens distortion tool there. But I can't find such a tool in Darktable. In Lightroom 6, I can manually adjust for simple barrel and pin-cushion distortion without having to select a lens profile, and with prime lenses this is more than enough to get the desired result. In any case, sometimes I don't want perfect correction, but a bespoke adjustment for the photo in question. I know that, for as-yet-unprofiled lenses, I can provide sample photos and request that a new one is created - but, that's time consuming. Darktable has the "Lens Correction" (Lensfun) tool, but that relies on already-existing profiles. ![]() not to a huge degree, but sometimes enough that I want to correct it. Some of these lenses exhibit barrel or pin-cushion distortion. ![]() I should explain, I shoot a *lot* of different lenses - mostly vintage Soviet glass, but plenty of other stuff too. However, there's one processing function I just can't seem to find an equivalent for, and it's making my workflow very clunky. I love it, and (for me) it's easily capable of replacing Lightroom 6 - at least so far as RAW development is concerned. So, after trialling Darktable 2.2.5 under Linux Mint for a few days, I'm completely sold.
