What is noise reduction in photo editing?

Image noise reduction or “denoise” is the process of removing digital noise from a picture. Noise distortion is unique to digital photos and is particularly common in photos taken in low light situations. It creates a grainy or pixelated look in pictures and in some cases can cause spots of discoloration in an image. Denoise therefore helps to minimize distortions for a more natural-looking photo.

Color noise

Color noise is a type of noise that causes colored blotches or flecks in a picture. It usually appears in areas of shadow in an image.

  • Move the color noise slider to the right to reduce color noise in a picture.


Depending on what device you used to take your picture, you may want to adjust the noise reduction radius. The radius slider sets the amount of denoising around each pixel. A higher radius will make the image look smoother but could also lose some details.

  • Move the slider to the right to increase the radius, or to the left to decrease it.

Tip: A lower radius is best for photos with fine details, taken with a high-quality camera. A higher radius is often better for smartphone pictures or photos with coarse details.

Adding sharpness

Sometimes denoising a photo can cause it to lose sharpness, but don’t worry as you can easily resharpen an image:

  1. Staying in the “Correction” tool, click Sharpness
  2. Move the slider to the right to increase sharpness
