Video: Sharpening edges

We're going to talk a little bit about edge sharpening right now, which is another of the bricks in the Adjustment pane available to you in Aperture. Edge Sharpening is very interesting. Basically, what it does is it restores the illusion of sharpness that's sometimes lost in the whole digital imaging process. I want to show you how this tool works in Aperture. So, first thing we're going to do, why don't we go to full-screen mode? We've been working a lot in some other previous adjustments in the regular Aperture interface.

Sharpening edges

We're going to talk a little bit about edge sharpening right now, which is another of the bricks in the Adjustment pane available to you in Aperture. Edge Sharpening is very interesting. Basically, what it does is it restores the illusion of sharpness that's sometimes lost in the whole digital imaging process. I want to show you how this tool works in Aperture. So, first thing we're going to do, why don't we go to full-screen mode? We've been working a lot in some other previous adjustments in the regular Aperture interface.

But now I want to work in full-screen mode too, and we'll go back and forth, so you can get a feel for both environments. So, I'm going to work on this image right here. I'm going to hit the F key, and that brings this into our Full-Screen mode. Then I'm going to hit the V key, and that opens it up. So, now we have this lovely shot in front of us. The reason why I chose this is I thought that this area here might illustrate the differences in sharpening quite well. So, let's see how that works.

Now I'm going to hit the H key, and that brings up our heads up display, our Inspector. This is very much like the Inspector that we worked with in the other mode, except it's a little bit prettier. But the functionality is almost the same. I want to do edge sharpening. Well, that is not one of the default bricks here. So, I'll go up to Adjustments, and we'll go down here to Edge Sharpen. We will add that brick to our image.

I think to really get a good look at what we're doing, let's go ahead and just zoom in on an area. We'll zoom in right here. So, I'm going to hit the Z key, and that will bring us up to 100%. So, I mentioned earlier that Edge Sharpen really creates the illusion of sharpness. The way that it does that, it actually increases the contrast between the brights and the darks right at the edge. The Edge Sharpen brick in Aperture actually does that in three passes.

So, it's a very sophisticated tool. Now, the idea about Edge Sharpen is - and the reason why I like it as a tool - it does a good job of working with the contrast at the edges, but it doesn't really mess with continuous tones that much. So, unlike some other sharpening filters, you can add sharpening to your image and not increase image noise in the solid areas, such as sky or in the shadow areas. It's very sophisticated. Now it has three sliders here. So, the Intensity slider is really the amount of sharpening that's being applied.

That's pretty straightforward. So, the more that you slide that, the more sharpening that's being applied. You move that back and you can see there is less. If you watch this area here, you can see the difference between basically no Intensity and then moving that up here. If you really pay attention, you can see that really what it's doing is increasing the contrast in this area. This is more contrasty now than it was here. That's where that illusion of sharpness comes from. So, we'll move that back up to here.

Now the edges are exactly that. This is working with the contrast at the edge of the image. So, as I move it, you can see that we're getting more and more contrast. So, I move it back, and we have less contrast. So, we move it up. We have sort of a very contrasty appearance. Now, Falloff is a very interesting slider. I mentioned, at the top of this, that Edge Sharpen actually sharpens in three passes. The first pass does the bulk of the sharpening, but then there are two more passes, and that's what Falloff controls.

So, Falloff controls the effect of that second and that third sharpening pass. So, you can actually move the Falloff slider to control that. So, if you want more of those second and third passes, you move the Falloff over to the right, and if you want to go primarily with the first pass, then you move the Falloff to the left. So, I think that it's a refinement, if anything else. So, for instance, we move Falloff all the way back, and we're looking mainly at the first sharpening pass here.

I like the first sharpening pass, and I think it looks pretty good. Then if I bring the Falloff up too much from those other sharpening passes, then suddenly I think we're starting to get this over-digital kind of phony look. So, a lot of times I'll have my Falloff more down here and maybe have these set a little bit higher. Now, I'm exaggerating right now onscreen, because I want you to be able to see this effect. But normally my settings would be something probably more like this.

Now let's turn Edge Sharpening off and on. Hopefully, you'll be able to see a difference. I can see difference right now as I work. Then if we exaggerate everything, you'll definitely be able to see a difference. There is off, and there is on. Notice how that contrast really increases, and that's really the magic of Edge Sharpening. Now we're looking at this at a high magnification. Normally, you would not be looking at your image this way, or it'd be just like gianormous. So, I'm going to go ahead and hit the Z key now that we've made our adjustments and move back.

And now we have a more natural looking view of this edge sharpening. So, basically what it does is it increases contrast at the edges, and that creates the illusion of sharpening, and you have three sliders here to control the intensity of that effect.
