How to increase video quality by removing noise?


In this Photo Retouch tutorial, we’ll look at how to reduce the appearance of noise in an image, including luminance noise, color noise and even jpeg artifacts, all using the Reduce Noise filter, first introduced in Photoshop CS2 (which means you’ll need at least CS2 to follow along). Notice that the name of the filter is Reduce Noise, not Remove Noise. As powerful as Photoshop is, there’s still no way to take a noisy image and clean it up completely, at least not without removing most of the detail in the image along with it. Any time we shoot in low light, use high ISO settings, or leave the expensive dSLR at home because the compact camera is easier to carry, there’s a good chance we’ll be dealing with noise. Fortunately, while we can’t remove it completely, Photoshop’s Reduce Noise filter still does a good job of reducing noise without sacrificing important image detail. Let’s see how it works.
