Digital photos shot at high ISO speeds often suffer from noise. And all digital photos have a slight softness due to the nature of imaging sensors. Like all imaging software, Adobe Lightroom and Photoshop have features for fixing these flaws. But using these features isn't always straightforward—and incorrect use of them can make a photo look artificial and overprocessed.
In this course, join Photoshop senior product manager Bryan O'Neil Hughes for an in-depth exploration of the noise-reduction and sharpening features in Lightroom and Photoshop. The course begins with tips for getting the cleanest possible images when you shoot. Next, Bryan details the process of making overall noise and sharpness improvements in Lightroom. The course concludes with a look at various advanced Photoshop techniques for localized adjustments and more.
We've talked a lot about how to fake restoring focus when an image isn't quite in focus, and there are a lot of really neat ways to do that. With an image like this as I mentioned before, we can increase the contrast, we could play around with the clarity, and doing those things will give the impression that the image is a little bit sharper than it is. But there is a really unique solution that was recently introduced in Photoshop, and it's a lot of fun to play around with. It's especially fun to take your old images and try playing around with it. It only works on images that were taken at a slower shutter speed where there's camera shake, which in a mobile environment or a low light environment, is actually pretty common.
So let's take a look at how this works. I'm going to hit Cmd+E to pop over to Photoshop. Here's my image, and we'll zoom in just a little bit. And I can see that there's the motion blur in the background, but it's kind of uneven. And that tells me that the camera was moving when the shot was taken. There're different parts of the image that are blurred different ways. So anything I do uniform to it isn't really going to work. Well, there's a really neat feature in here under the Sharpen menu called Shake Reduction. And if I come in here, it's going to automatically look at this image, and you see it does something kind of miraculous.
It's looking at the image and it's removing the camera shake from it. And, there's a lot of controls here, but what's great about this is it really does work automatically. What it's doing is it's tracking the motion in the image, and it's removing it locally. It's finding the area where the motion blur exists and it's taking it away. Now in this particular image, that comes on a little strong. So I probably want to smooth that out a little bit, back it down a little. But if I were to toggle the preview, I'd see that it definitely worked in this image, and it did something I could never do with sharpening or clarity or anything like that.
So, I encourage you try your images that were shot at low shutter speeds, because those are the ones that are going to show this sort of camera shake. And in a lot of cases, you might have to play around with it a bit. You'll notice that you can choose a particular area of the image, and run it again, and it will analyze just that area and get different results. And you'll have a controls for smoothing and suppressing artifacts, but play around with it and see how it works. You might find that you can save a file that you thought was unsalvageable before.
