Sharpening and noise reduction
Sharpen a photo
You sharpen photos at two stages in the Lightroom workflow: as you view and edit photos, and when you print or
export them. Sharpening is part of the camera default that Lightroom automatically applies to your photos.
When Lightroom exports, prints, or rasterizes a photo for editing in an external editor, the sharpen setting for the image
is applied to the rendered file.
1 In the Develop module, zoom in on the photo to at least 100%.
2 Drag in the Navigator panel to see an area of the photo that highlights the effect of the sharpening adjustment.
3 In the Detail panel, adjust any of the following Sharpening settings:
Amount Adjusts edge definition. Increase the Amount value to increase sharpening. A value of zero (0) turns off
sharpening. In general, set Amount to a lower value for cleaner images. The adjustment locates pixels that differ
from surrounding pixels based on the threshold you specify and increases the pixels’ contrast by the amount you
specify.
