Google's new camera app brings Photo Sphere and Lens Blur to Android devices
While Google has continued to toss new features into the camera app shipped on its Nexus devices, many Android phones replace it with something else. But just as we revealed a few weeks ago, now it's available in the Play Store, ready to run on any phone or tablet using Android 4.4 KitKat. Beyond bits like Photo Sphere that we've seen before, Google is filling in the blanks on its new "Lens Blur" option. Meant to emphasize the subject while blurring the background for an impressive depth of field effect, it uses algorithms to simulate the large camera lens and aperture your phone or tablet doesn't actually have. Taking the photo requires an upward sweep to capture multiple images, used to estimate the depth of objects for a 3D map that lets the software re-render the photo later and blur specific items based on where it thinks they are. Google's Research Blog has more details on how it's all done, including the Lytro-like ability to change which object is in focus after you take the shot.
Microsoft algorithm uses six-axis motion sensors to fix blurry snapshots, inadvertently pimping your ride
Trying to snap a shot of your cherry red Mazda, but can't keep your hands still? You'll find all the tech you need to smooth things out in an iPhone 4 or (MotionPlus-equipped) Nintendo Wiimote. Experimenting with 6DOF inertial measurement sensor packages, scientists at Microsoft Research have developed a software algorithm that literally records your exposure-destroying shake via accelerometer and gyroscope, then magically removes the blur by canceling it out. While the technique still isn't perfect -- spot ghostly line above some of those background cars -- the Microsoft researchers compared their results to other in-progress algorithms, and we think you'll agree this new solution presents the best results by far. It's a shame Microsoft doesn't say when we'll see the tech in a spiffy DSLR attachment, or better yet a cameraphone.

How to use Photoshop's Lens Blur tool with masking (Part 2 of 2)
Yesterday, I showed you how to simulate a photograph taken with a tilt-shift lens by using Photoshop CS3's Lens Blur tool. Today, we'll do something a bit more practical: clipping out an object that's not entirely in focus. Clipping out objects that are out of focus can be something of a chore: either you have a hard, dark edge somewhere you don't want, or you have to settle for feathering the whole thing, leaving edges that should be sharp a little too blurry. We'll be clipping out this old book, and dropping it on a new surface.
How to use Photoshop's Lens Blur tool for tilt-shift fakery (Part 1 of 2)
We all know Photoshop is a powerful tool. In two tutorials, I'll take you through how to use Photoshop CS3's Lens Blur filter to do two things: today, we'll make images look like they were shot with a tilt-shift lens. Tomorrow, we'll create clipping masks for objects that aren't entirely in focus. Lens Blur gives the effect of a narrower depth of field, so some areas of your image stay in focus, and other areas are blurred. Combined with an alpha channel that defines areas of blurriness, you have a powerful way to create masks and alter photos. The easiest thing to do is show you first how Lens Blur works in pictures.
