I love when the effect I'm trying to accomplish is incredibly fast and easy to apply, and that's certainly the case for a very basic effect with Find Edges. If you apply the Find Edges filter, you might initially assume that it's not really all that useful, but it actually can be blended with an image in a variety of ways that make it quite interesting, I think. I have an image here that is sort of more painting than photograph, you might say. It has a zoom and blur effect that makes it not look exactly like a photographic image. I'd like to create an even more dramatic effect, making it look a little more painterly utilizing Find Edges. Let's take a look at how it's done.
I'll start off by creating a copy of my Background Image Layer. So I'll Drag the Thumbnail for that Background Layer down to the Create New Layer button at the bottom of the Layers panel. And then with that Background Copy created, I'll go to the Filter menu and I'm going to choose Stylize followed by Find Edges. Now, you'll notice that the Find Edges option on the menu here does not have an ellipsis. It does not have the three dots after the last word. And you'll notice that most of the other filters do. What that signifies is whether or not there are settings that you can choose from for that particular filter. The Extrude filter, for example, does have settings and you see the ellipsis there.
So you have an indication that there will be a dialog displayed with settings that you can adjust. But for Find Edges, there is no ellipsis, there are not settings to apply. The filter simply processes your image. And that's it. I'll go ahead and choose that command, and you can see the result is rather dramatic, it has indeed found the edges in the photograph, all of the contrast edges in the image. And it has enhanced those, the original color is still there, but we have a lot more contrast along those edges, and most of the rest of the image has been made white.
There are a variety of ways we can have this interact with the original image, if we'd like. In this case, for a type of painterly effect, what I would typically do is reduce the opacity for this background copy layer. In other words, reduce the opacity for that Find Edges effect, so that the original colors in the photo can show through just a little bit. Now, I would tend to keep the opacity setting relatively high. I just want a little bit of that original color to show, because keep in mind if I reduce the opacity too much then that Find Edges effect will disappear as well. So I'll use a relatively high opacity, just letting a little of the original color show through.
To blend with those enhanced edges. So you can see incredibility simple to use that Find Edges filter. But of course then you can find additional creative ways to fine tune the overall effect.
