Get brighter greens, cooler blues and more with our guide to mas­ter­ing Nikon Cap­ture NX-D’s LCH panel

Cap­ture NX-D doesn’t have se­lec­tion tools in the way that Pho­to­shop and El­e­ments do, but you can still use it to ad­just

in­di­vid­ual colours. It’s all done with the Light­ness, Chroma and Hue, or LCH, panel. Those terms may not be fa­mil­iar, but if you use Pho­to­shop or El­e­ments, you’ll prob­a­bly have used the Hue, Sat­u­ra­tion and Light­ness ad­just­ments. Th­ese are the same thing, ex­cept that Nikon uses the word ‘chroma’ in­stead of ‘sat­u­ra­tion’.

Nor­mally, you edit images in RGB mode. The photo is split into red, green and blue colour chan­nels which you can ad­just all at the same time or in­di­vid­u­ally. Of­ten, though, it’s much more use­ful to split the colour data into light­ness, chroma and hue val­ues in­stead, be­cause this gives you much more con­trol over in­di­vid­ual colours.

In Pho­to­shop’s Hue/Sat­u­ra­tion di­a­log you can choose the colours you want to al­ter with a drop-down menu, while in Cap­ture NX-D you se­lect them from a colour spec­trum. Oth­er­wise, the prin­ci­ple is very much the same. If you want to deepen a blue sky, for ex­am­ple, you can re­duce the light­ness val­ues of the blue tones in the pic­ture and in­crease the chroma – you can see this at work in our main an­no­ta­tion. It’s also pos­si­ble to shift the hue of par­tic­u­lar colours with­out chang­ing the bal­ance of the whole pic­ture.

The best thing about this tech­nique is that it doesn’t re­quire any selections or masks. They’re not needed be­cause you’re iden­ti­fy­ing par­tic­u­lar colours, not par­tic­u­lar ar­eas of the pic­ture. Cap­ture NX-D doesn’t tar­get pre­cise colour val­ues. It works across a colour range, blend­ing in your ad­just­ments with sim­i­lar colours so that you get a much more nat­u­ral-look­ing re­sult. If you do want to tar­get colours more pre­cisely, how­ever, you can add ex­tra con­trol points to the ad­just­ments in the Light­ness, Chroma and Hue pan­els.
