(De)Saturation Techniques: 2
Following on from part 1
The left column are reference images: the original at the top, then an orangy duotone, then an orange/green tritone.
The middle column: at the top, a blue colorization layer, then the two duotones, all applied in a Hue blend mode.
The right column is the same as the middle column, but is using marcus’ technique (technique 3 from part1) to desaturate the less colourful parts of the images. This also eliminates the colour casts from the shadows and the chips in the background wall.
