Interesting video about the master Ansel Adams darkroom techniques. As you can see in the video, he used to modify and improve his photographs using handmade techniques invented by himself. He was Photoshopping his pictures when computers were not capable of doing so. There is a scene, where you can see a tool used to underexpose zones of the picture, that resembles pretty much to the brush used in Lightroom. He was a genius of photography.
Also I would like to dedicate this video to all the people that usually criticize the digital manipulation of photography. For that people I want to say “remember that photography is an art by which you can express your story and your feelings”. He was doing so with the tools he had.
