Reduce noise in a photo in Photos on Mac
Photos taken in low light may appear with graininess or speckles, referred to as noise. You can reduce or eliminate noise in photos.
Note: You can also reduce noise in a video. See Change and enhance a video.
Noise reduction also works with photos in RAW file format.
In the Photos app
on your Mac, double-click a photo, then click Edit in the toolbar.
Click Adjust in the toolbar.
In the Adjust pane, click the arrow
next to Noise Reduction.
Drag the Noise Reduction slider until you’re satisfied with the results.
Note: When you edit RAW images (RAW version 6 or later), Luminance Noise, Colour Noise and Detail sliders appear for fine-tuning noise reduction.
