One of the most exciting things I think modern photography has is the ability to make special effects thanks to the computer. I have always been fascinated by mixing colour with blank & white elements. So, after a fast reading of the Darktable 3.2 manual, I found a way to create the effect I wanted: blank and white but one colour.
Who doesn't remember that dark scene of the Schindler's List film where a girl in a red jacket is walking? Then a few minutes later, you identify her corpse from a pile of bodies. Well, I will show how to make this happen, but with a more joyful image.
The picture above was taken by me with my Canon 90D in the last Christmas Parade 2020 in my local city. The left picture is the original JPEG from the camera, the middle one is the product of the RAW processed with Darktable and the right one is the same photo with the additional effect of a monochrome photo while keeping red-orange colours. There it is what I did.

It is very disappointing when you are shooting mixed scenarios where there are dark and light areas all over it. Photos are not right, bright parts are overexposed if you want the dark ones to appear or dark areas are underexposed because bright parts look good. For example a sunset, a moon landscape or even a Christmas tree. Our eyes are used to seeing in HDR mode but the camera doesn't capture what we see, after all, it is just a sensor.
HDR images are the kind of images that have managed to let you enjoy the dark and bright parts of a scene. They are the product of a post-edition.
In this article, I will explain how to produce an HDR photo taking advance of the AEB capability of modern digital cameras and post-editing with Darktable. Please note I am a Canon user, if I use their terms just translate them to other brands. I am also an open-source advocate myself, so do not expect me to write for any other commercial proprietary software.
These photos were taken using a Canon 90D using a prime lens of 50mm f/1.8. The camera had the D+ enabled (a personal preference; thus, ISO 200 is the minimum I could use). The EXIF information is as follows: 1/10s, f/1.8, 50mm, ISO 200.

If you are into Linux and Photography (some of us are) and you, like me, have a not-very old Canon camera, you may see that the RAW files are no longer CR2 files, but with extension CR3. CR3 raw format is the new replacement for CR2 that comes with all Dig!c8 (or better) chipsets. In my very specific case, with my Canon 90D and R6.
I was amazed by the quality of this camera (I come from a Canon 200D aka SL2 that has a Digic7 chip). Canon did a good job from version 7 to 8. However, here comes the issue, I saved my photos in CR3 format, and when going to my desktop, neither KDE/Plasma nor Darktable (current version 3.2.1 when writing this article) were able to recognize it. Windows is not an option for me.
UPDATE: Since Darktable 3.8 you can open CR3 files If you compile it with exiv2 version 0.27.4 with BMFF support enabled through its RawSpeed library.
