Be selective about colour
James Paterson demonstrates how to selectively remove colour in Lightroom
Use Lightroom to selectively remove colours, leaving a couple for impact
Making selective colour effects in Lightroom is a quick and easy task. The key to success is the HSL panel. The eight colour sliders enable you to zero in on different colours in the image. You can adjust the Hue, Luminance or (as in this case) the Saturation to remove any colours you don’t need.
The HSL sliders target colour ranges rather than specific areas, so you’ll probably need to mop up any remaining colour. For example, in our image removing saturation in everything but the reds and oranges almost does the job of leaving the phone box in colour while the rest of the image is in black-and-white. However, there’s still some orange present in the buildings. It’s a quick fix: a few strokes of the Adjustment Brush loaded with -100% saturation is all that’s required. Once that’s been done, we can complete the image by adding a vignette, enhancing the tones and sharpening the details.
