His­togram

01

This is an in­dis­pens­able guide to the ef­fect of your ad­just­ments. You can use it to ad­just the Ex­po­sure Com­pen­sa­tion slider and get the best tonal range out of your RAW files, and you can check it to make sure any fur­ther tonal ad­just­ments you make don’t cause ‘clip­ping’.

Ex­po­sure Com­pen­sa­tion

02

RAW (NEF) files con­tain ex­tra tonal range com­pared to JPEGs, and you can use the Ex­po­sure Com­pen­sa­tion slider to make use of this. It’s not ‘real’ ex­po­sure com­pen­sa­tion – you can’t al­ter the cam­era’s ex­po­sure set­tings af­ter a shot has been taken – but it’s of­ten enough to res­cue small ex­po­sure er­rors.

Tone

03

The Tone but­ton is split in two. The left side dis­plays the Tone panel, which has Bright­ness, Con­trast and Sat­u­ra­tion slid­ers, just like those you see on the cam­era when you mod­ify the Pic­ture Con­trols. How­ever, they’re not very sub­tle, and there are bet­ter ways to mod­ify your im­ages.

Tone (De­tail)

04

The right side of the Tone but­ton dis­plays the Tone (De­tail) panel. This is quite in­ter­est­ing be­cause it has slid­ers for High­light Pro­tec­tion (re­cov­er­ing clipped high­lights), Shadow Pro­tec­tion (re­cov­er­ing shad­ows) and D-Light­ing HS – this Nikon’s sys­tem for bring­ing out darker tones with­out af­fect­ing the rest. We’ll look at these op­tions in a fu­ture tu­to­rial.

Lev­els & Curves

05

Cap­ture NX-D’s Lev­els and Curves panel of­fers much more subtlety and con­trol than its Tone panel. You can use curves ad­just­ments to change the bright­ness and con­trast of your im­age with­out clip­ping any im­por­tant shadow and high­light de­tail, and the panel also dis­plays the his­togram, which will help you judge where to place your curve con­trol points.
