Keep the noise down

NPhoto - - Nikon Skills -

1 Im­prove the ex­po­sure

Open noise_s­tart.dng in the Li­brary mod­ule. Tog­gle open the Meta­data tab. To take this shot we used a noise-in­duc­ing ISO12800. Zoom in to see the noise more clearly. In the De­velop mod­ule, drag Ex­po­sure to +1.75, set Blacks to -64 and Vi­brance to +29.

2 Re­duce colour noise

In the De­tail panel’s Noise Re­duc­tion sec­tion, drag Color to 0 to see the chroma noise speck­les. Slide it to 25 to re­move them. The De­tail tab pro­vides a bal­ance be­tween re­duc­ing colour bleed and colour speck­ling. Drag it right to re­duce bleed or left to re­duce speck­ling.

3 Re­duce lu­mi­nance noise

The Smooth­ness slider is de­signed to re­move low fre­quency colour mot­tling, but in this case the de­fault set­ting of 50 gives good re­sults. To soften the re­main­ing lu­mi­nance noise, drag the Lu­mi­nance slider to 32. This re­duces lu­mi­nance noise, but it also blurs im­age de­tail.

4 Pre­serve the de­tail

The De­tail tab en­ables you to get a bal­ance be­tween smooth­ing out lu­mi­nance noise while pro­tect­ing de­tail. Drag it right to sharpen blurred de­tails, or left to blur noise. The de­fault of 50 pro­duces an ef­fec­tive com­pro­mise. You could also try in­creas­ing Con­trast.
