SHARPEN DETAIL AND REDUCE NOISE
Reveal delicate details while smoothing out luminance and chrominance noise
Before and after
To see how your sharpening and noise reduction processing is shaping up, click here to display ‘before’ and ‘after’ versions of your photograph.
Give it 100%
To see how sharp your shot is (and to spot luminance and chrominance noise more effectively), you need to view the image’s actual pixels. Right-click on the image to summon the pop-up menu and choose View at 100%. You’ll then be able to remove noise and sharpen details much more effectively using the sliders in the Unsharp Mask panel. This operation will cause the images in the before and after panels to zoom in.

Unshar p Mas k
Click on this icon to summon the Unsharp Mask panel. The term sounds illogical, but the Unsharp Mask tool derives its name from a traditional analogue darkroom technique designed to create a sharper look.
Here we’ve zoomed in 100% to give you a closer look at the unprocessed photo’s pixels. As well as a slightly soft-looking logo you can also see rainbow speckles of chrominance noise in the vintage bus’s radiator grid.
Better Quali ty
The Noise Reduction panel enables you to apply a Faster noise reduction method, but choosing Better Quality will help you eradicate more examples of chrominance and luminance noise. This option is especially useful if you’re trying to process a photo to sell as a stock image, as the presence of noise can cause a site’s quality control inspectors to reject your image.
Intensi ty and Sharpness
The Noise Reduction panel’s Sharpness slider helps you get a balance between smoothing out noise while keeping important details looking sharp.
Intensi ty and Radius
The Unsharp Mask pane’s Intensity slider increases the contrast around the edge of details in the image. This helps details such as our bus’s logo pop out and look sharper.
The Radius slider increases the spread of the contrast change. If you push these sliders too far you’ll see harsh black or white lines appear around contrasting edges. Follow our tutorial below to understand (and learn how to avoid) artefacts such as halos.
This slider reduces the combined effect of the Intensity and Radius sliders, so it helps you get a balance between sharpening detail while keeping image-spoiling artefacts at bay.
