# Denoise
All images contain noise, so denoising is a classic image processing function. The challenge, however, is to remove noise while keeping fine details. The denoising algorithm in Astra Image is very good at separating and preserving details while removing noise.
The Denoise tool.
**Luminance noise**\
This setting sets the strength of luminance noise removal. Higher values produce a stronger result, but the minimum value that removes the noise adequately should be used to preserve as much detail as possible.
**Chrominance noise**\
Here you can set the strength of the chrominance noise removal. Higher values produce a stronger result, but the minimum value that removes the noise adequately should be used to preserve as much detail as possible.
