Click and hold inside the preview area to see what the image looked like originally, then release your mouse button to see how much noise reduction has been applied.
All we can do is try to make the image look better than it did originally.įirst, start with the Strength value set to 0%, then slowly drag the slider towards the right while keeping an eye on the image in the preview area until as much of the luminance noise as possible is removed.
#REMOVE COLORFINALE ISO#
In my case here, there's no way I'll be able to make an image shot at ISO 2000 look just as clean and smooth as if I had shot it at ISO 100 or 200. Removing luminance noise is a simple two-step process, but remember, we need to have realistic expectations. Finally, we have the Remove JPEG Artifact option (blue) for reducing the appearance of jpeg compression artifacts:Īll those black, white and gray speckles are luminance noise. Sharpening images, which is what this slider does, is better handled with one of Photoshop's actual sharpening filters, like Unsharp Mask or Smart Sharpen, so I'd recommend lowering the Sharpen Details option down to 0%, effectively turning it off. Below that is a slider we're not going to look at, Sharpen Details (not colored), since it has nothing to do with reducing noise. Next is the Reduce Color Noise slider (yellow), which, as you may have guessed, reduces color noise. I've colorized the sections we're most interested in.įrom top to bottom, the first two sliders, Strength and Preserve Details (colored in green), are used to remove luminance noise, which we'll look at shortly. Even though it's not so obvious, the column along the right is actually divided up into different sections, with each section affecting a different type of noise. The Reduce Noise dialog box contains a large preview area on the left so we can see what we're doing (although we can also see what we're doing in the document window itself as long as the Preview option is checked, which it is by default) and some sliders and options along the right.
I haven't done anything with the image yet other than cropped it a little: Here's an image I have open on my screen, taken a couple of years ago while walking through Animal Kingdom in Disney World. Let's see how it works.ĭownload this tutorial as a print-ready PDF! 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. 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.Īny 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. Notice that the name of the filter is Reduce Noise, not Remove Noise.
#REMOVE COLORFINALE HOW TO#
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).
