Long ago when I had a darkroom and made my wet prints (I have no place for it anymore) I also hand colored them, which was great fun and I really miss it. So lately I did some experiments to color my B/W photos again but now in a photo editor. The intention was to get attractive pictures from an artistic point of view, not to perfectly reproduce the effect at any cost. However, when using subtle tones the result is very similar. These photo's are depicting an unused house and an unused gate respectively, both surrounded by dried out weeds, which is colored light brown. Here is what I did: 1. An extra layer is added to the photo in the editor, in which all the modifications are made. 2. The area to color is selected with the Rectangle, Free Selection, or Magic Wand Tool. 3. The selected area is filled with a (very) transparent color (Tolerance=100, Opacity=5..10). 4. Optionally details from the colored area can be cut out again to keep them uncolored. 5. The layer is merged with the photo and the result is saved. Adding a color reduces contrast so if needed you can increase the contrast again when the area is still selected, but this is only needed when Opacity has a large value. This is also basically what you do when a print is hand-colored; adding very transparent layers until areas have the right hue. Edit 27/09/17 - Description for photos added, p.s. removed.
