Introducing the darktable app store - Today we are happy to announce a big new feature that we will not only ship with the big 2.0 release later this year but also with our next point release, 1.6.4, which is due in about a week: even more darkroom modules! One of the big strengths of darktable has always been its varied selection of modules to tweak your image. However, that has also been one of the main points of criticism: too much, too many and too complicated to gr... http://ow.ly/2WKwQo

Finally stepping the game up!

I always wondered why darktable was delivering so few. This store is all what DT was missing to let users finally get professional results from their pictures /o\

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: Normally, if w... http://ow.ly/2TxZJM

+Peter Teuben No method works for all photos. Personally, when I use these masks, I go further and limit the selection even more (combination of luminosity and hue, for example). However, for the few times I tried this, I didn't get sharp transitions (ugly, perhaps - but not sharp).

+Andreas Katifes Yes, as mentioned in the article. However, as Istvan mentioned, for strong effects (large changes to luminosity, or saturation),  it'll lead to halos. The point of the article was to provide a more natural transition.

+Dave Jones  Yes, that's what I used to do, and ultimately the "luminosity mask" is simply taking that idea to a larger extent. But your approach of having a small "mismatch" in the triangles still created halos  in a number of photos. I just didn't think to move the triangles much further.

Thanks for this nice tutorial
 
An awesome tutorial courtesy of +Ian Hex has just been published!

Ian walks through using luminosity masking in darktable to target adjustments based on a tonal region of an image.

#FOSS   #photography   #postprocessing  
Luminosity Masking, the ability to create selections of your image based on its specific tones for ultra-targeted editing, is a relatively recent concept favoured by landscape photographers the world over. In this article, we will explore how to create and use Luminosity Masks in the F/OSS RAW ...

Color Reconstruction - 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 I’d like to summarize how dar... http://ow.ly/2VDsgE

Nice, very nice.

I didn't understand how do you apply the Bilateral Filter for "Invalid Pixels" because the "Color" value isn't known, what do you compare?
Or do you use the other channels as reference to calculate the weight?

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 about how an image w... http://ow.ly/2UBnAO

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 process darktable has been added a print module. The print module Nothing fancy there, ju... http://ow.ly/2TTroW

+Danas Anis Everybody would like to have this functionality, but AFAIK this is not as easy to do (right) as it may look/sound. From what I've gathered the script produces some questionable output as well at times (and it even requires specific type of images as input according to the link)
