In the previous movie, we began our conversation about working with the shake reduction filter. And there we copied the layer and then applied this filter to that layer, and Photoshop created for us a blur estimation region. What I want to do in this movie is build upon what we already know. And I want to talk a bit about how we can get a bit more advanced with this. Let's double-click the zoom tool to zoom into 100%, and let's focus in on this driftwood heart that the bride is holding right here. We have some controls which allow us to deal with the texture or the noise that we have in the photograph.
For starters, you'll see that there is a radio checkbox right here. We want to make sure that we turn that on to enable the artifact suppression. The reason why you want that on is because you can always control the amount right here. If ever you want to remove the artifact suppression, we'll just drag this down to 0%. So again I recommend you leave that enabled and then you customize the amount down below. Now how do both of these sliders work? Well, artifact suppression, when you bring this up, what you'll discover is that it reduces noise that's brought into the image that's larger, larger problems.
The Smoothing slider, on the other hand, deals with the smaller issues, like the little teenie noise. As we drag this down to the left, we'll see more of that show up. As we drag it up to the right, we're going to see less. With this area of the photograph, I think having a little bit of that texture in there is okay. Also bring down my artifact suppression a little bit more as well. Once we've chosen the setting for this, we have to wait for it to render the results. Then we want to click on our Preview check box to see.
Well, here's the before, and then here's the after. Looks like we could use a touch more smoothing here as well. So I'll just bring that up, a little bit. Again, when working with this tool, you have to be patient, and keep in mind that it's doing some amazing things behind the scenes to try to improve the photograph. Alright, well, what about working with another blur estimation region. Why would we want to do that? Why would we want to create another? Well, for a moment, let's zoom out. You know, often what can happen with optics is you can have an area that is sharper, say in the center of the frame, and more out of focus near the edge, especially if you're shaking or moving the camera.
Sometimes you'll have different degrees of blur in one image. So you can click on this icon here to have Photoshop choose another area, and then begin to analyze it. You can always customize this too, if you want to bring this in to really focus in on the face. And one of the advantages of doing this is that it's now applying multiple adjustments to different areas, and you can further customize what you're seeing in that area. So here I'll zoom in on the photograph, we'll zoom up to the face area, and get nice and close there so we can see all of these details.
In this area, if we want more smoothing, perhaps we want less of the texture of the skin to be brought out, we want it to be nice and clean and smooth, we can bring that up. And the smoothing and artifact suppression values are different based on the various estimation regions. For example, let me go ahead and bring these values up. Let's say we bring them up approximately to 30. They're both 32 or 30. If we go down to this other area and activate this estimation region, you can see that these are both about 22.
So again, we have the ability to customize how that area is being affected. Another thing we may want to do is ask ourself, well, is this actually helping? Who knows, right? We don't necessarily know, but we can see a before and after if we click in this little center box there to disable that. Wait for it to render the preview, and take a look. And here, you can evaluate. Does this look better or is it better if we click to turn that back on, and see how that's going to make some additional corrections to removing the blur in the photograph.
Often, you can find that one is enough. Yet, in certain images, having another can be helpful. In this one, I'm just going to bring these values down just a little bit here, I think I went a touch too high on those. And then I'll click on my Preview checkbox to see the overall. Here's our before, and then now here's the after. With images like this which have a slight blur, shake reduction can help out a lot. What about those photographs that are incredibly blurry? Well, it just can't save the day, so there is a limit to the technology at this point.
And if you find yourself really wrestling with a blurry image, before you delete it, you may want to experiment with this filter. Now to apply these settings, as always, just click OK. It will then render and apply those settings to the layer which we targeted, which is the layer which is titled Sharpen. And on that Sharpen layer, we now have our shape reduction sharpening applied.
