Di­ag­nose ex­po­sure prob­lems and im­prove the dy­namic range of your images us­ing Nikon Cap­ture NX-D

file con­tains more im­age data than you ac­tu­ally see. In par­tic­u­lar, the RAW file may con­tain ad­di­tional shadow and high­light de­tail which you can bring out to im­prove the tonal range of your pic­tures.

You can ac­cess this us­ing the EV Com­pen­sa­tion menu in the Edit panel. Our sam­ple shot, above, was un­der­ex­posed, but an adjustment of +1EV has in­creased the bright­ness, and the de­tail in the darker ar­eas, so our Lev­els and Curves ad­just­ments have got a bet­ter im­age to work on.

Lev­els, Curves and EV Com­pen­sa­tion can all blur into a con­fus­ing set of al­ter­na­tives, but there is a log­i­cal work­flow. EV Com­pen­sa­tion, if it’s nec­es­sary, should be the first step.

Next, use the Lev­els & Curves di­a­log to check the his­togram. If there’s any ‘dead’ space ei­ther side of the his­togram, you can drag the edges of the box in­wards so that the his­togram fills the space. This is a Lev­els adjustment, which is step two.

Step three is Curves ad­just­ments. Th­ese aren’t al­ways nec­es­sary, but they can im­prove the look of the pic­ture in cer­tain cases. You change the shape of the curve us­ing ‘con­trol points’. Our an­no­ta­tion, above and right, shows you how it’s done, while our step-by-step guide, bot­tom­right, gives you more ex­am­ples.
