A new digital photo format from Microsoft : HD Photo

A new digital photo format that offers higher-quality images with better compression will soon submit to an international standards organization according to Microsoft.

The format, named HD Photo was previously known as 'Windows Media Photo' will rival the industry standard JPEG format, a 15-year-old technology widely used in digital cameras and image applications.

Both JPEG and HD Photo formats take images and use compression to make the file sizes smaller so more photos can fitted in lesser size on disk or memory card. Trade of to this is quality loss. But, Microsoft claims HD Photo's lightweight algorithm causes less damage to photos during compression, with higher-quality images that are half the size of a JPEG.

The format can also accommodate "lossless" and "lossy" compression, two methods of compressing photo data with different effects on image quality. Microsoft said adjustments can be made to color balance and exposure settings that won't discard or truncate data that occurs with other bit-map formats.
