>> Male Speaker: Let's take a look at Smart Sharpen in action. Back to the disney_concert_hall image. And I'll click on this layer and navigate to Filter > Sharpen > Smart Sharpen. Okay, let's take a look at what happens here. I'm going to reset all these settings. Okay, let's that a look at how this works. We're clicking on the Advanced tab because we'll be using that from now on. I'm going to increase the Amount and the Radius in a way that's exaggerated.
We wouldn't typically have a Radius this high. Typically the Radius is going to be pretty low, and we want to make sure we're on Lens Blur. And so, with an exaggerated Radius, we see the dreaded halo. How then can we get rid of that? Let's go to the Shadow tab and watch as we increase the Fade Amount, Tonal Width, and then Radius, or reach. Look at what happened in this part of the image, the sharpening there when I increased the Tonal Width. I'm fading that amount right off.
I'm able to reel it in, and I'm able to reel it in with a combination of those sliders. Let's go to the Highlights tab. Look at the highlight. The halo we have here again, watch as we increase our Amount and then our Tonal Width and then our Radius. What we're able to do here is essentially reel that in or remove that. Bring that way back, and we're able to do that because we now have access to the Shadow and Highlight tab inside of Smart Sharpen. So they combined a couple of things here for us.
And it works really well. Let's work on an image. We're going to go ahead and open up the image peppers.psd. And copy the layer, Command+J, name the layer "smart_sharpen". Navigate to Filter > Sharpen > Smart Sharpen. And what you want to do when you're sharpening is typically bring things back to normal and start from scratch.
We're on the Advanced tab. We have an amount. We're going to increase our Amount to approximately 100. And then bring up the Radius. And we're going to exaggerate the Radius until we see the image start to fall apart and then bring it underneath that. A little bit like tuning a guitar, right, go back and forth. Now some of us may be thinking when do we use the More Accurate button. Well let's take a look at the image. Exaggerate it for a second. Notice the artifact that I have here in this image, the pixelization I can see due to the sharpening.
When I check More Accurate, that's exaggerated. Very interesting. So what this means is that more details will be sharpened, which sometimes is helpful. If the image was captured in really good lighting, and the quality is there, definitely More Accurate will be better. With this lower and More Accurate on, we're not going to see the noise exaggerated as much. We will see those lines defined a little bit better. Let's go back to 100 percent. And then you'll want to make an evaluation on your computer how that more accurate does.
But it will give you stronger lines. But beware; it can also exaggerate noise or cause pixelization, posterization, and those types of effects. Once we've done that, we want to go to the Shadow tab and dial in the Fade Amount, Tonal Width, and Radius. And typically these travel together. Take the fade up first, then the highlight, very similar thing in this image. There's isn't a great need for any of these. We'll go ahead and click on the image. That will give us our before and then after.
I think I need to remove a little bit more of the highlight, so I'm going to increase the Radius and then click on the image before and after. I'm seeing some haloing in there. And the shadows as well. Click OK and then let's look at our before and after. It does a really amazing job of sharpening. I tend to like to go a little bit higher than I would be comfortable with because I know that I'm going to back it off.
And we don't have the same need to use the blend mode of Luminosity. Because that's now built into Smart Sharpen. Remember in Unsharp Mask I said you want to take the layer to a blend mode of Luminosity. It's now built in, yet it's not quite as effective as the blend mode of Luminosity. And let me show you why. So I have exaggerated the sharpening like mad, and we see color artifacts there, right? So if I take this to Luminosity, it's going to fix that.
Of course my color now looks pretty crazy because of the way that I sharpened the image. But at least that's not going to have those color artifacts. So you will hear some people out there say, don't worry about taking your layer to a blend mode of Luminosity. It's now built into Smart Sharpen. And that is true except it doesn't do as good of a job as Luminosity. So I still use it. I think it's a great technique to have, and it's a wonderful way to be able to sharpen your images and not exaggerate noise.
