There is another really useful tool that we can use when we're interested in working on a larger area of our photograph and when we want to make a linear adjustment. You know, in the previous movie we worked with the radial filter, which allowed us to create an elliptical shape, and then to affect the area inside or outside of the shape. What about if we would just want to select an area in a linear fashion. Say the top po, portion of this photograph. Maybe we want to affect that in one way. We want to sharpen up that area. And then we want to soften and reduce the noise in the lower area.
Well we can do that by working with what's called the graduated filter. Yet before we get to the graduated filter, let's double click the zoom tool to evaluate the details that we have in this photograph. When we double-click the zoom tool, it takes our zoom rate to 100% then we can press the space bar key and click and drag around to view what we have here. In this image, I noticed that it's a little bit soft and there's some luminous noise that we need to deal with. So lets start off with the detail panel. In the detail panel I want to increase the amount of the sharpness and then reduce the detail slider and increase my masking.
I want to perform some basic input sharpening. And then on top of that we're going to look at how we can use the graduated filter. Let's get rid of some of that luminescence noise that we have in the photograph by working with these sliders. And already, I think the photograph looks good. And here we've corrected this portion of the image. I'll press the space bar key and go down to the lower area. We've also corrected this part. We can see the before and after, the noise which we had in this area, and the detail. And then up here, we can see how we've corrected the noise and the detail as well.
With this, I want to apply a really moderate amount of sharpening, so it's kind of just a general amount of input sharpening. So here's I've dropped my amount back down, because I'm going to add or layer on top of this, another level using the graduated filter. In order to work with that tool though, we need to zoom out. One of the ways I like to do that, is to double-click the hand tool. That takes us to a fit and view mode of this beautiful, interesting, seaside resort here.
Well to work with the graduated filter, we can click on the icon which is located right next to the radio filter or you can press g to select the tool. Here you'll encounter that we have the same settings that we've seen in some of our other tools and so again, let's take the same approach. We'll click on the plus icon for sharpness and then we'll increase the sharpness value and decrease some of the noise reduction. And as long as I'm going to apply this sharpness and noise reduction, I might as well effect the color. So here I'll increase my color temperature.
Maybe add a little bit of saturation, just for fun as well. Well, the way that this tool works is what you can do is click and drag. In order to really see how it effects an area of the image. I want to exaggerate my exposure slider for just a moment. And here, I'm going to decrease the exposure. This won't look very good, but it will help us understand the tool. Take a look. Now we click and drag. As I do that, you can see that the top area of the photograph is being affected. I can rotate this in order to have it affect different areas.
If I drag further, there's more of a transitional edge. If I keep these close together, it's a harsher, or it's a more defined transition. We also have some overlay graphics which we can see. The first one is a green circle with a green checkered line, that's where this effect is modifying the image at full intensity, then it tapers off to the red circle, and the red checkered line. Well here, I want to bring this down little bit further, so that it's all the way to the edge of the pool, and then it slowly fades off to that area.
Now I don't want this to darken the sky, so let's bring this back to where it was. We'll just, we can even just double-click it to bring it back to zero. What I do want to have happen is that it warns up this part of the image. That it increases my saturation there. It sharpens that area and reduces some noise. So here we can see that's our before and then now here's our after. It's a subtle adjustment but nonetheless it's allowing us to improve a larger area of the photograph.
Well that is step one. And we've gotten to a good point where we've improved that part of the photograph. We still have one more step to take with this image. So let's keep this file open and continue our progress in the next movie.
