Why don't you provide a Windows build?

Due to the heated debate lately, a short foreword: We do not want to harass, insult or criticize anyone due to his or her choice of operating system. Still, from time to time we encounter comments from people accusing us of ignorance or even disrespect towards Windows users. If any of our statements can be interpreted such, we want to apologize for that – and once more give the full … Continue reading

If you overexpose a photo with your digital camera you are in trouble. That’s what most photography related textbooks tell you – and it’s true. So you better pay close attention to your camera’s metering while shooting. However, what to do when the “bad thing” happened and you got this one non-repeatable shot, which is so absolutely brilliant, but unfortunately has some ugly signs of overexposure? In this blog article … Continue reading

On Lens Detection and Correction

darktable (and some other projects, like for example ufraw) don’t do any real lens detection or correction by itself. We depend on two libraries which in most cases are provided by the Linux distribution you’re using. Lens Detection Many image files contain metadata about how the image was created. In case of digital camera images, a standard called Exif is used, this standard allows a camera to record many details … Continue reading


Print Module

After being in the camera our pictures deserve some love and to be shared. Every photographer will tell you the joy of having a picture in the hands. At last the pixels have taken form on a piece of paper to give birth to a photography which can be put on the wall! Though, printing is not easy, there are many technical aspects to take into account. To streamline this … Continue reading


Luminosity Masks in Darktable

Pat David has a great blog on photoediting in GIMP. I recently read his post on luminosity masks and was fairly impressed. Can darktable do something similar? Yes – they’re a special case of parametric masks. I thought I’d post a quick tutorial on luminosity masks using parametric masks. First, I strongly suggest you read Pat David’s post and thoroughly understand what’s going on. A quick and simplistic explanation follows: … Continue reading

Of Histograms and Waveforms

People using image editors or similar (raster) graphics editors are probably familiar with histograms. You also have them in almost all digital cameras. In darktable you can find it very prominently in the top right corner of darkroom mode, but also as a backdrop of modules like levels, tonecurve and similar. From a mathematical point of view they are a diagram displaying the amount of pixels in the image that … Continue reading
