Join Chris Orwig for an in-depth discussion in this video Using Shake Reduction, part of Photoshop for Photographers: 2013 Creative Cloud Updates.
Now that we know a little bit about Shake Reduction, let's take a look at how we can use this powerful new feature. Here's a picture that I captured early in the morning, in a low light scenario. I was hand holding my camera and I captured this image at one 20th of a second. So if you zoom in on the image, it looks good but it's not quite sharp. In order to zoom in on this photograph, I'm going to double click the Zoom Tool, I want to take this image to 100%, then press the Space Bar key and click and drag in order to move around the image. Now again here, the image looks okay, but it's just not tack sharp. And so what I want to do is use shake reduction in order to improve this photograph.
And the great thing about shake reduction, is that what it's going to do is actually fix the camera shake. You know, sometime if you sharpen a soft image, it's kind of like cleaning a broken window. Well, it doesn't fix the main problem, but, camera shake, well it goes right to the root of the problem, fixes it a nice way so that everything looks better. Alright, well in order to work with camera shake, what we want to do is navigate to our Filter Pull Down Menu and then go to sharpen because it is a sharpening filter and then choose the top option there, Shake Reduction.
This will then launch the Shake Reduction dialogue. Alright well, here in our Shake Reduction dialogue, we have some tools, we have the image preview area, then we have some controls in a detail preview over here on the right hand side. Well first I want to focus in on how we can evaluate, some of the shake reduction results by zooming in on the image, using the detail panel. Notice that the detail panel allows us to change the zoom rate. The default zoom rate is 100%, or one time zoom, here we can click an drag around.
I'll click and drag around so that we can focus in on this fisherman, who is bringing in some crab which he has recently caught. Well it's nice to be able to see this 100% view, here using the detail panel and you can change the area that you're focusing in on here, by clicking on this icon here. When you reposition the cursor over the image, it allows you to view the image in different ways. If ever you want to select an area, to stay in focus in the detail panel, we'll just click on that and what it will do is it will lock that area into the detail preview.
Now, you can also undock the detail panel. To do that, click on this icon here and here you can see we can simply click and drag this around in order to reposition how we're zooming in on the image. As I mentioned, Photoshop automatically takes a look at your photograph and tries to find an area to analyse to figure out the camera shape. And you know what, it's done a pretty good job. Here in the loop, if we click and hold we can see the before, and then let go and you can see the after. I know that this may be difficult to see, so I'm going to zoom in four times, to 400%, just so that we can see some detail here.
Here's before, and then I'll let go, and there's after. Now another way that you can work with this, which is even more effective, is to go Advanced mode. When you're in Advance Mode, it allows you to have a better preview because here every time I move the loop, it's actually going to just show me this small area. So if we open up Advance Mode, what will happen is we can then look at the area that it's analyzing. So here for a moment, I'm just going to move the loop down below and you can see this is the region of interest, this is the area it's analyzing in order to try to correct the photograph. We can also dock the loop, if that's distracting, you can do so by clicking on the X icon and that will then dock it over here. If you want to use the loop, you can always click on this icon here and then hover over the image until you get to the area that you want to focus in on and then click in order to lock that in the preview.
Click and hold to see the before, let go to see the after. To undock the loop, you can either press the Q key, or you can click on on this icon, which allows us to then move the loop around and evaluate the photograph. Another way that you can view your image, is by simply zooming in on this particular area, the preview of the photograph here. One easy way to do that is with the Zoom tool. Here I'll click on the Zoom Tool to select it, then I'll go ahead and just click a few times in order to zoom in on the photograph.
And in this case, I'm going to zoom all the way to 100%. Then I'll use the Hand tool, and click and drag to pan around. Now, I can see much more of the photograph. When you click and hold, this allows you to, then, drag around, and to see your preview, just click on the Preview check box, to look at your before, and then, now, the after. Now because this image was in pretty good shape, it may be difficult for you to see the before and after, but on my monitor it looks awesome. All right well let's zoom in a little bit further so you can what's happening here. I'll grab the zoom tool and I'll click a few times by this fisherman here and you can see he's bringing in some crab and what I want to do is focus in on some of the noise that I'm noticing in the background.
Well, if we remove this or if we take our Smoothing and Artifact Suppression Sliders all the way down, what we're going to see is we're going to notice much more noise here in the background. Photo Shop or render this out for us and now I can see that you know what, while this is improving the photograph, it's also introducing some noise. Again click on the preview button. We can see there's a before, it's soft, blurry, it doesn't look very good. Now here is the after, it is sharper but we have issues or problems with the noise. Well this is where smoothing, and artifact suppression, come in to save the day.
Now smoothing will help us to remove all of these little teeny details in the background, they're now completely gone. Artifact suppression, that deals with some of the larger artifacts that we have in our photograph. You almost always will want to start off with smoothing, and then do artifact suppression, second. Also I should point out that, for the most part, Photoshop will do a good job at determining how to remove this in the default settings of 20% approximately, well typically they work very well. Well after we've dialed in our settings, and after we've determined that Photoshop has done a good job with this shape reduction, in order to apply thee settings, all that we need to do is to simply click Okay and then Photoshop will render or apply those settings onto the layer that we have selected.
