Once again, if you recall from the sharpening section, I'm going to hold on to the Alt key and slide it so that you can see how it changes using the grayscale view because it's much easier to notice that you'll notice it's blending it. So now what I'm going to do is I'm just going to adjust the slider. If you recall, luminance gives the kind of mottled and splotchy look to the image, and it introduces all this kind of green. I'm going to move the slider from left to right. Now that the noise slider has been adjusted, let's work now on the luminance noise reduction. Now you'll notice that it's a very, very subtle change, and you have to look at it very carefully just to see where the noise has been reduced. I'm going to show you the before view and the after view. Next, I'm going to use the smoothness slider just to smooth out all of these blemishes, make sure that it's okay. If I move it to the left, I'm going to blend in all of those details. By moving to the right, I'm going to bring out more detail. Now what I'm going to do is I'm going to work with the detail, I'm going to adjust the detail. You can see that there's just a slight adjustment. If we want, we can see the before and after look. But slowly, the image and the cover are becoming a more consistent color. I'm going to zoom in, and then I'm going to play with the noise reduction and the color slider so that I can bring some sort of consistency to the yellow notebook.Īs soon as I adjust to the color slider, the other two sliders for detail and smoothness will become available. The first thing that I'm going to do is work with the color settings and ensure that the notebook has some consistent color. Let's go back to the develop module and work now on reducing the noise. It's very, very high up on the ISO, and it's going to be very noisy as a result. You can see that this image was taken at a high ISO ISO 25 600. If you want to find out the ISO that this image was taken under, you have to go into the library module, check out the metadata, and then scroll down to the ISO speed reading. The way noise is introduced in most cases it's because we shoot at very high ISO settings. ![]() I'm not sure if you can see it clearly, but there's a little bit of green, yellow, there's some slight orange, and all of these things. That noise shows up in the variety of splotches of color that are within this book. The other kind of noise that we have is something called color noise. It has to do with the color values of this image. You'll notice all of the splotching and the kind of green that's introduced. The best way to identify luminance noise is to just zoom in to the image. Those are the adjustments that we are going to be making to this image. It includes luminance noise, and it includes color noise. Image noise also includes two kinds of noise. Now, what is noise? You might be wondering, well, image noise has to do with artifacts that we see within the image. That is, the more you sharpen an image, the more noise that you're going to be introducing into your final product. In another section, I mentioned to you how sharpening and noise reduction work together. Right now, we are in the develop module, and we've opened up the detail panel and will be working within the noise reduction area. You can find this image in your images folder. The example that we're going to use in this section is this example of this Xbox 360 controller. In this section, I want to share how you can use Adobe Photoshop Lightroom to clean up any noise that may show up in your images. In this exercise, we will learn about Adobe Lightroom Classic Noise Reduction. Product: Adobe Lightroom Classic | Subject: Adobe Photoshop Lightroom Classic
