Now, as I mentioned in a previous section on adjusting sports images, don't do your sharpening in Lightroom. Do it in Photoshop. So that's what we're going to do here. This image needs to be sharpened, but it needs to be sharpened in a certain way to bring out certain elements of the image, so we're going to open this up in Photoshop to show you how to do this. I don't want you to get in the habit of sharpening in Lightroom. You're just going to be unhappy with the results. So here we have our image and we want to sharpen these areas here and then we also want to sharpen the star tracks. Look at all the color that's in there. Your eye doesn't see that. That's one of the great things about night photography. Timed night photography is the things that you see that the human eye cannot pick up. Alright, so we're going to go to our Layers area, establish Layers. Then we're going to go to our middle, disconnect the top, come up here, rather, and get our unsharp mask. We're sharpening only for this area here. We don't care about the sky. So we're going to take this threshold out, back to zero. You know what? Before we do this, we need to change the size of this image and the resolution is 240. This is going to go on the Internet, so I'm going to make this one 650. So, we go back to our layer and then we choose the unsharp mask. That looks real good. Now, the problem you have is in this top area, we don't want to boost the noise, so we're going to go up here, establish a layer mask. Let's go fit on screen. We're going to close this down. We're going to come get our brush and we're going to go for 100 Percent opacity. We're just going to paint over and that's as simple as that. Now we're going to combine these two layers, merge them together, establish another copy, and then we're going to sharpen for this area here, again looking at only the middle layer. Get our unsharp mask. This time, we're going to add a threshold of 2 so that we don't reach down into the blue and pick up noise. We want to avoid that noise, yet we still want these star tracks to have a nice sharpen. Now, you'll notice that it's over-sharpened down here on the bottom. That's why we established a new copy layer, because what we're going to do is we're going to establish another mask, only this time we're going to reveal the top. So you don't need any more sharpening on that bottom area. Now, just to review, we had a 0 threshold here and we had a threshold of 2 on our sharpening settings up here, so this is, you know, these are the things that Lightroom cannot do and has a very, very hard time with, sharpening. That's why I say do it only in Photoshop, but there, in a nutshell, is how to adjust this image and look how good that looks. Those star trails are very, very sharp. There's lots of color in there. We've got a nighttime scene that looks like a nighttime scene, with lots of detail in the trees. That's a great little image, if I do say so myself, so that's how to do sharpening. Once you get all your other adjustments done in Lightroom, bring them into Photoshop.
