Microsoft Moves in on the JPEG

Ah, but then Microsoft would own the international photo standard. I can see why MS would want to push this, but I do not see this as a good thing. For example, the .doc standard, whilst not accepted as the international standard, is the most widely used, and is also insecure and unstable. (The true international standard for text, though, is the .rtf, which does not have as many features!)

Adobe is also working on a digital negative standard.

Microsoft Corp. will soon submit to an international standards organization a new photo format that offers higher-quality images with better compression, the company said today.

The format, HD Photo -- recently renamed from Windows Media Photo -- is taking aim at the JPEG format, a 15-year-old technology widely used in digital cameras and image applications.

Both formats take images and use compression to make the file sizes smaller so more photos can fit on a memory card. During compression, however, the quality of the photo tends to degrade.

Microsoft said 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.

RAW is about as true-to-source as you can get, but point-and-shoot cameras lack RAW functionality for the most part.
