In this video by Photoshop Universe we learn how to reduce noise in a photo in Adobe Photoshop. First we learn that there are two types of noise in a photo, luminance and color noise. Next we learn that reducing noise is balancing act, as we take away noise we also lose some detail of the image. Finally the author goes over the 3 steps it takes to reduce the color noise that can be present in photos. Using these methods we learn that we can quickly clean up images that have noise in them in Photoshop.
