Get crisper-look­ing shots while avoid­ing adding arte­facts

NPhoto - - CONTENTS -

Sharpen up del­i­cate de­tails in your pho­to­graphs with­out un­nec­es­sary arte­facts creep­ing into your shot

1 MAGNIFY IM­AGE

Browse to our sup­plied sharp­en_s­tart.nef im­age in Cap­ture NX-D’S Fold­ers panel. To see how sharp a shot re­ally is, choose View>view at 100%. Use the Hand tool [H] to po­si­tion the net of sea sponges as shown, so you can also see some of the back­ground of the im­age, too.

2 UN­DER­STAND ARTE­FACTS

In the Edit panel, click the Un­sharp Mask icon. Drag In­ten­sity to 100 to in­crease edge con­trast. Drag Ra­dius to 100 to in­crease the spread of the edge con­trast change. Now you can see sharp­en­ing arte­facts, such as clipped black and white haloes, and noise in the back­ground.

3 SIDE BY SIDE

Re­duce the slid­ers back to 0. Click the Multi icon and choose Com­pare Be­fore and Af­ter Im­ages. Click the Orig­i­nal icon to see the soft start file in the left win­dow. In the Un­sharp Mask panel, drag In­ten­sity to 70 and Ra­dius to 30 for a more sub­tle but no­tice­able sharp­en­ing ef­fect.

4 RE­DUCE NOISE

The In­ten­sity and Ra­dius ad­just­ments have teased out more de­tail in the net and sponges, but they’ve also ex­ag­ger­ated noise in the back­ground bokeh. By drag­ging Thresh­old to 5 you can limit the amount of sharp­en­ing in these blurred ar­eas and re­duce sharp­ened noise arte­facts.
