However, it’s equally effective when used through Lightroom or Photoshop. There are many procedures for this, but all attempt to determine whether the actual differences in pixel values constitute noise or real photographic detail, and average out the former while attempting to preserve the latter. The following images demonstrate the effects of various types of noise reduction, exaggerated for clarity. Clunky UI, frequent crashes, and exporting issues.

If you don’t want to rely entirely on DxO, you can always install it as a Lightroom plugin rather than downloading the standalone program. It’s less expensive than competing asset managers, but certainly doesn’t lack in editing resources. Noise reduction controls are fairly limited. Since the charge created at each photosite is linearly proportional to the amount of light that hits it, the maths works out that the brighter areas of the image have significantly more data than the shadow areas. Open the Detail panel to reveal the Noise Reduction slider. Also often there is only one noisy image available.
