"Windows Media Photo" in Beta: Microsoft veröffentlicht "HD Photo" Plug-in für Adobes "Photoshop"
Microsoft hat die neueste Beta-Version seines "HD Photo"-Plug-ins für Adobes Bildbearbeitungs-Klassiker "Photoshop CS2" und "Photoshop CS3" auf "Windows XP" und "Windows Vista" vorgestellt. Die Software kann bis zum 30. August kostenlos benutzt werden. "HD Photo" (oder "Windows Media Photo") ist Microsofts neues Dateiformat für Photos, das doppelt so effizient wie JPEG sein soll - und das bei deutlich besserer Bildqualität, so der Software-Hersteller.

HD Photo, also known as Windows Media Photo, is a new file format for continuous-tone still images that surpasses the limitations of existing image formats. HD Photo supports a wide range of features, including:
- Multiple color formats for display or print
- Fixed or floating point high dynamic range, wide gamut image encoding
- Lossless or high-quality lossy compression
- Extremely efficient decoding for multiple resolutions and sub-regions
- Minimal overhead for format conversion or transformations during decode
HD Photo delivers a lightweight, high performance algorithm with a small memory footprint that enables practical, in-device encoding and decoding. HD Photo delivers image quality that is comparable to JPEG-2000 and more than twice the quality of JPEG.
Windows Media Photo has been renamed as HD Photo. Both names refer to the same file format. Some Microsoft Windows products still refer to the HD Photo implementation as Windows Media Photo.
This download contains version 1.0, the released version, of the specification and is fully compatible with the version of HD Photo (Windows Media Photo) that is currently shipping with Windows Vista, Windows Image Component (WIC), and .NET Framework 3.0.

HD Photo Feature Specification 1.0
The HD Photo Feature Specification provides detailed information about the file container format and includes information about the overall structure, the wide range of supported image pixel formats, and the metadata. The specification also contains information about the application program interfaces (APIs) that are available in Windows Vista, such as Windows Image Components (WIC) and .NET Framework 3.0 for earlier versions of Microsoft Windows. The HD Photo Feature Specification and the corresponding Windows development documentation provide developers the information they need to implement HD Photo support in Windows applications, services, and device drivers.
The HD Photo Specification does not document the compressed bit stream format. That information is provided in the Device Porting Kit (DPK). Note that the DPK includes the HD Photo Feature Specification. If you are interested in both you can just download the DPK.
