Let's continue to take a look at how we can use the radial filter in order to correct or enhance our photographs and in particular with this photograph, what I want to do is take a look at how we can use the filter in order to darken the edges, in order to create a bit of a vignette effect. This is a portrait that I captured of Angus Stone, a famous musician. I like the portrait but I just wish those edges where a bit darker. Let's take a look at how we can do that using the radial filter. Press Shift+M to select the radial filter or click on the circle icon here in the tool strip.
When you open up the radial filter you may encounter that the sliders are in positions which you don't really like or want. You can always reset the sliders by double-clicking on the icon here or if you hold down the Opt key on a Mac, or Alt on Windows, that will change the word Effect into Reset, click on that and it will reset all the sliders back to their default zero settings. What kind of effect do we want to apply here? We want to darken the edges. Now in order to illustrate a few things about how this tool works, I'm going to exaggerate for a moment so this won't look good, but stick with me.
We're going to take my exposure all the way down to -4. Next what I want to do is click over the center part of the image and then I'll click and drag out so that we can see we have this darkening effect. Now this is over the top, it doesn't look good. I wanted to do this to illustrate another slider that we have which is Feather. Now if I hide this overlay by pressing the H key, I can then change my Feather amount and really see the edge here. If I take it down to 0, you notice that this is a really hard or fixed edge.
If I bring this up, we can then soften that edge. How far you go with this will really depend upon the effect or the area that you're working on. Next I'll press the H key, again, to bring back this overlay. I could of course extend this all the way to the edge, all the way to the borders of this image but I want to do this really quickly. One easy way to do that is by a way of a keyboard shortcut combination. If you're on a Mac, press and hold Cmd, if you're on Windows, press and hold Ctrl, then double-click on any radial adjustment and what it will do is it will extend it to the edges of your photograph.
In this way, I now have the darkening effect being applied to this part of the image. Now that I've done that, I'm going to go ahead and lessen the effect a little bit. Also add a bit of warmth to that area and then I'll darken the shadows as well. Here I've made a number of different adjustments, and at a certain point, you may want to modify all of those adjustments together. In other words, let's say that what you want to do is sort of scale this effect back because it's a bit too strong. Let me show you what I mean. I'll press the H key, to hide the overlay and then I'll click on the toggle switch, here's my before and then, here is my after.
I like the effect but it's just too strong. Rather than modifying each individual slider, what you can do is something which is awesome, you can collapse this view of all the sliders. That will then show you your Amount slider and with the Amount slider you can then change the overall intensity of all of the sliders together. So here, as I bring this down I have less of that effect. I can find just the right spot for this effect. Click on the toggle switch, now you can see here is the before, and then the after. What exactly is this Amount slider doing? Let me show you.
Let's drag this down further and then let's open up our sliders. As you can see it brought all of these back closer to the default setting of zero but it brought them back relative from where they were. We'll go ahead and collapse that again and then I'll bring up my amount and then here as I open this up you can see where those are now. As you can see, by being able to control your overall amount, it can really help you dial in a particular effect. Before we wrap this up, one thing that I realize is that I wish my effect was just out further to the edges.
One way to be able to do that is to actually click and drag on these anchor points and extend this beyond the edge of the photograph. In this way you can see how we can really control where this effect is going to be applied to the photograph. Sometimes modifying the shapes so that it works well with your image can really make all the difference in the world so that you have exactly the desired effect that you're going for. All right, well here I'll press the H key, then I'll press the black slash key to look at our before and after, here is before and then now here is after.
