![]() Last but not least, you’ll need to set the amount of sharpening to be applied after the noise reduction process is complete. Because color noise presents itself as a sharp color variation from the surrounding pixels (for example, a single stray red pixel in a blue sky is probably noise) this slider doesn’t have a separate Preserve Details slider. Next, you’ll need to determine the amount of color noise reduction. It sounds simple, but it can be a difficult decision to make in practice! Most of your noise reduction efforts will be spent on balancing these two sliders against each other until you’re satisfied with the results. It uses contrast edge detection to determine which areas of your image need to be isolated from the blurring effect caused by the Strength slider. This one is a bit more complex since it acts as a modifier to the Strength setting, but it is also well-named.

Noise is one of the most frustrating aspects of digital photography, but since it’s such a common issue, there is now a wide range of solutions available to help you control the noise in your images. Over the last two decades, I’ve spent countless hours removing noise from my images with a variety of techniques, and I can help guide you through the process.
