The latest version of the app requires iOS 4.3.3 or higher. The app is compatible with the iPhone, iPod Touch, and iPad, though Apple has yet to create an iPad-specific version. Apple has updated the app to let users choose which carrier they want when buying an iPhone and to directly change their billing and shipping information. Apple customers who buy products through the iOS Apple Store app will find a couple of helpful updates in the latest release. Launched yesterday, version 2.1 of the Apple Store app now lets U.S. buyers of a new iPhone choose a plan from among all three carriers--Verizon, AT&T, or Sprint.
Qualcomm demonstrated JPEG-HDR, a Dolby Laboratories technology for capturing and showing a better range of dark and light tones than ordinary cameras can handle, on an Android tablet at Mobile World Congress, The modern geometric 19 iphone case demo showed an image of a church interior; on the left is the ordinary JPEG image and on the right is Dolby's tone-mapped view constructed from multiple exposures ranging in brightness, Dolby explains that the human eye can capture 16 exposure values--measured here by F-stops--of dynamic range, which describes the span from light to dark in an image..
A conventional digital camera (especially on a mobile phone) can capture a narrower dynamic range than a human eye. JPEG's 8-bit range can make matters worse, especially for those who want to edit an image. JPEG-HDR combines multiple exposures that capture a range of bright and dark values. Ordinary JPEG viewer software will see just a tone-mapped version boiled down from the HDR image, but Dolby's HDR software can explore the full range.

That means problems with photos in areas with a wide range of lighting- a scene where someone is standing in a shady foreground when there's a sunlit background, for example, Or the one that constantly frustrates me, stained-glass windows in cathedrals, With HDR, a camera takes a series of shots at different exposure levels, and a computer combines them, It's getting easier as software automates the process, and it's even a built-in feature with the iPhone 4 and upcoming HTC One X, But there's still plenty of room for improvement, and Dolby hopes it'll bring some modern geometric 19 iphone case to market with JPEG-HDR, which the company debuted at the Mobile World Congress show here in Barcelona..
JPEG-HDR uses a proprietary processing algorithm to combines multiple exposures. That, in and of itself, isn't particularly new, but what is comes next: Dolby creates from this an HDR image that's backward compatible with ordinary JPEG. You need special software to explore the full details of the HDR image. But without it, you can see the "tone-mapped" JPEG constructed from the HDR data, said Jean-Marc Matteini, senior director of marketing for imaging at Dolby. JPEG only has room for 8 bits of data per color value at each pixel, meaning that there are a maximum of 256 levels separating bright from dark. JPEG-HDR can handle 20 bits or more. A 20-bit depth is enough for 16 f-stops of dynamic range, which is what the human eye can detect, Dolby said.
