Join Deke McClelland for an in-depth discussion in this video Correcting camera shake with Shake Reduction, part of Photoshop CC 2013 New Features.
In this movie, I'll introduce you to Photoshop's newest experimental feature which goes by the name Shake Reduction. And it's job is to correct for camera shake in a scene, by which I mean you've got a handheld camera, low light, and the movement in the scene is caused by you the photographer. Not by the subjects of your photograph moving. And Shake Reduction relies on a high degree of artificial intelligence. It's a pretty amazing feature. Sometimes it gets it right. Sometimes it doesn't. And often times it varies inside the confines of a single photograph. So I'll go ahead and press Ctrl+1, or Cmd+1 on a Mac, to zoom in to this image that I shot in low evening light.
You can see that we've got a ton of camera shake going on. Now you can apply Shake Reduction as a smart filter. I'll go ahead and double-click on the background here and I'll call this new layer camera shake, and then I'll click OK. Now I'll right-click inside the image window with the rectangular marquee tool and choose Convert to Smart Object so that we can apply a smart filter. Next, I'll go up to the Filter menu, choose Sharpen, and choose the very first command here. Shake Reduction, which brings up this whopping big dialog box. And notice that right away, the filter goes ahead a takes a stab at automatically correcting the image.
And it does so differently for every single image that you'll open. And if you want to see the difference you can just turn on and off this preview checkbox. So, this is the before version of the image with the shake and this is the after version. You can zoom in on your image if you like by pressing Ctrl+Plus or Cmd+Plus on a Mac. And you also have this loop over here in the right hand side of the dialog box. To reposition the preview inside the loop, you can drag it like so or you can just click at a different area inside of the larger preview.
And then, if you want to use that region in order to apply a correction automatically, then you click on this little button. Enhance at loop location, and you'll end up getting an enhancement designed specifically for this portion of the image. Now, it may not suit all of the image and in fact in our case it really doesn't. The reason being, even though this is a very obvious area of camera shake. Because it's an open sign with some lights around it, so these big B&Q (INAUDIBLE) of lights are actually tiny blurred lights.
Problem is, that this filter doesn't work very well with blown highlights. So when you have specular highlights like these, things aren't going to work out so well. So instead what I'm going to do is click at this location where there's a person behind the window there. And I'll go ahead and click on that Enhance button in order to enhance this location instead. Now notice that you have some numerical options here. This blur trace bounds that defines the size of the blur, and camera shake sets that up automatically for the image unless you think you know better.
You're generally better off leaving that option alone, and then you can apply some smoothing as well. If you want to smooth some of the details inside of the image, to compensate for any noise or artifacting that's introduced by the sharpening. Notice we don't have an amount value. So really smoothing is as close as you come. Then you've got artifact suppression which will get rid of large weirdnesses in the scene. Unlike with most filters, you're going to get a lot more work done by ignoring the numerical options and adding some automatic enhancements. And you do that as follows.
The first the you want to do is double-click somewhere inside the larger preview in order to undock the loop and move it into the image preview. And then you can drag that loop around and notice that as you're dragging it, you're seeing the original version of the image and as soon as you release, you're seeing the compensation. Notice also you've got this little advanced area right there. Go ahead and twirl that open cause it's very, very useful. You'll see the area that's being used in order to enhance the image. And right now it's just this little square area. The area that I clicked on and then enhanced.
And you can even see the shape on the blur. And if you want to see it better you click on this little icon here in the lower right corner and then you'll see a larger version. So we're seeing the shape of the blur represented in white against a black background. Now, if you want to add more areas of interest to your image, then one thing you can do is just click on this little icon, add suggested blur trace. And then the camera shape filter will go ahead and automatically add an area like so. You can also modify the size of that area if you want to just by dragging on one of these handles. If you want tot change the location of this region, then you drag on this little center point.
Now you can see another blur preview down here in the advance region and that represents the selected rectangular region. And if you want to get a sense of what's going on there you can click on the little bottom right icon to zoom right in. So each one of these represents a different region. Notice when I click on this one it's selected, and that selects this square region. If I want to add yet another one, I would just click on this little Plus icon. You never know where these new areas are going to crop up, because Shake Reduction is just making this stuff up on the fly. Or, if you have an area that you think might be interesting. Then you can just go ahead an drag around it, like so. Using this rectangle tool right there, which is selected by default. An now notice that, that did actually a pretty darn good job. If I move the loop, over that a, at the end of the word pasta, notice how very blurry it is, but as soon as I release I can see that Photoshop has done a really great job Of redrawing the A.
So sometimes it does a great job as we're seeing right there, and other times, it's an interesting job anyway. And what you may find this useful for by the way, in addition to trying to correct an image which may not be this filter's strong suit, you may find that it's useful for figuring out what in the world the words in an image are. For example, this telephone number down here is very difficult to read. But as soon as I release, it becomes a little more clear exactly what those numbers are.
One more way to use this filter, by the way, I'm going to go ahead and zoom in on the word restorante up here at the top. I'll press Ctrl+1, Cmd+1 on the Mac, to zoom in to 100%. You also have this tool right there. This little blur direction tool, It's only available by the way, when advanced is twirled opened. Because if it's closed, then that tool will appear dimmed. So I'll go ahead and twirl, advanced back open. You really want to work with advanced all the time, by the way. And then go ahead and select that tool. And what you can do, notice that automatically turns off the preview checkbox so that you can draw along an edge that you know is total blur, like this edge of the E right there.
And that will set a blur trace length and also set a trace direction. Now, if you want to change that on the fly. Go and zoom in here a little bit. Then you can press your bracket keys. The right bracket key makes this guy longer and this is the square bracket key by the way. The left square bracket key makes this guy shorter and then if you want to change the angle, you press the control key or the command key on the Mac. And press one of those square bracket keys. That's Ctrl+Right Bracket, Cmd+Right Bracket on the Mac and this is Ctrl+Left Bracket or Cmd+Left Bracket on the Mac. And then to see what in the world's happening, you need to turn the preview checkbox back on and we'll end up seeing this effect here. Not my favorite effect where this image is concerned. So, if you don't like something you've come up. Of course, you can delete it.
Or you can just turn it off. This is our blur line right there. I'm just going to turn that guy off. The one that I drew manually. And you can see we end up with a better effect without that manual modification. Go ahead and press Ctrl+0 or Cmd+0 on the Mac to zoom out from preview. And if you want to dismiss this little loop, you can click on the Close box there, or you can just press the Q key to quit it. And that'll go ahead and lock it down in the lower right corner of the dialog box. And by the way, the dialog box is too big to totally fit on the screen.
That's why it's getting cut off down here at the bottom. Once you've made all the modifications you think you might like, go ahead and click on the OK button in order to accept that change. And now notice the word pasta, it's in pretty good shape here. So this is the original version of the photograph, which I can see by turning off the smart filter. And this is what it looks like now. Thanks to the highly experimental, artificial intelligence, provided by the Shake Reduction filter.
