CONTROL TONES WITH SELECTIVE COLOUR
When you convert your shots to mono, you turn anything that’s coloured into grey – but how bright or dark that grey tone is in the black-and-white mix can be controlled. A blue sky, for example, can be processed to appear as a near-white, very light grey through to a very dark grey that’s close to black, or any tone in-between. This is all achieved using the colour sliders in a raw converter like Camera Raw or Lightroom; or you can do it in Photoshop by creating an Adjustment Layer and selecting Black & White. Just move the sliders for each colour to set the tone as you see fit. Practice makes perfect, so try some options.
