How to reduce noise in a photo
- Choose or drop a photo. It opens with Noise reduction set to 50.
- Zoom to 100% and adjust Noise reduction until the grain calms down. If you see colored blotches, raise Color noise as well.
- Save from Export.
Good to know
- Color noise is the red and green speckling in dark areas; it can usually be removed completely without any loss of detail.
- Too much noise reduction makes skin look plastic. Stop as soon as the grain stops distracting.
- Brightening a dark photo reveals noise, so reduce noise after you set the exposure.
Questions
Why are my night photos grainy?
In low light the sensor collects few photons, and the camera amplifies the signal, noise included.
Will it blur my photo?
It only averages pixels that are already similar, so edges and texture are kept. Very high settings will still soften fine detail.
Can I add grain back on purpose?
Yes. Film grain, under Effects, adds an even, film-like grain that looks far better than sensor noise.
