Let's take a look at how we can work on and improve some of the small details of this photograph. In particular, I want to take a look at how we can work with sharpening this file and also reducing some of the noise. Well, let's go ahead and make our way up to these tabs here. You can see that we're currently in Basic. We're going to go ahead and click on the next one, which is Tone Curve. Well, we've already really worked on the tonality of the image, so let's go ahead and skip that, move to the next one, which is Detail. Now here, you can see we can work on Sharpening and also Noise Reduction. So, I need to zoom in to 100% in order to really work on the sharpening of this image.
To do so, I'll double-click the Zoom tool and then press the Spacebar key to click and drag around so I can see some important information. What I want to do is have a view here of the face and also a bit of the background. Well, how then can I sharpen this? What I can do is go ahead and increase my Amount. As I do that, we're going to see that there is more and more of a sharpening effect applied to the image. What about Radius? Well, this is interesting. A lower radius, we're going to see that it's a smaller area of edge contrast. A higher radius, we're going to see that much higher, or more of a halo.
Typically, your Radius is going to be pretty, low somewhere less than 3. Now, Detail, what we can do is have less Detail sharpen, which looks better for skin. Masking, we'll go ahead and increase that to limit the sharpening to particular areas. All right! Well, what about Noise Reduction? Well, here what I can do is increase my Luminance Noise Reduction, making the background looking much more smooth, add a little bit of contrast back to that so that the image isn't too soft, and also bring up some of my Color Noise Reduction and then work on the overall color details by modifying this slider here.
Now, of course, we're going to dig much deeper into these controls later. All I'm trying to do here is simply introduce how we could use these here. All right! Well, let's click on the Preview check box, here we have our before and then after. Now, when we click on this check box, you're seeing a difference only in this particular panel, only for Detail, and this is really handy. What I want to do is zoom in on the background so that we can actually see the structure of the image here. See how it's changed. Again, here we have before, a lot of Color Noise and Luminance Noise, and now here we have after, the image looks much better. All right! Well, I've zoomed in too far.
If I want to zoom out to be able to see the whole image, I'll simply double-click on the Hand tool. That will take this image to a view that fits the entire image inside of Camera Raw.
