The picture above was taken by me with my Canon 90D in the last Christmas Parade 2020 in my local city. Well, I will show how to make this happen, but with a more joyful image. Then a few minutes later, you identify her corpse from a pile of bodies. Who doesn't remember that dark scene of the Schindler's List film where a girl in a red jacket is walking. So, after giving a fast reading to the Darktable 3.2 manual, I found a way to create the effect I want: blank and white but one colour. I have always been fascinated by mixing colour with blank & white elements. One of the most exciting things I think modern photography has is the ability to make special effects thanks to the computer.
