Today, Microsoft announced that it has formally offered HD Photo for consideration as an international standard by JPEG, the Joint Photographic Experts Group. If adopted as part of a larger effort called JPEG Systems, HD Photo would be known as "JPEG XR." The idea behind standardizing on the format is to give makers of digital cameras, printers, and displays—as well as software developers—both a single, consistent format to support, but also to ensure interoperability between products which support JPEG XR. And most importantly, if HD Photo is approved as a standard, Microsoft will offer royalty-free access to its patents which are required to implement HD Photo."</i><br /><br /><img src="http://www.digitalmediathoughts.com/images/Microsoft_s_HD_Photo_Proposed_for_JPEG_XR.jpg" /><br /><br />Finally. Frankly, JPEG is getting a little long in the tooth. If you've bought a high-megapixel camera in the last year (7MP or more), you've come to hate compression artifacts. Most of the cameras on the market today save to JPEG by default, and few even give you any other option. Hopefully JPEG XR will still keep the file sizes down while preserving more detail than JPEG does today. The proof is in the pudding however. I'd like to see a side by side comparison.

Meh. :?

JPEG2000, and every other "super JPEG" format has failed. Why? Because if you look at a basic quality JPEG from any camera on the market today, you'll have a very hard time finding artifacts (I guess we disagree there Jeremy). These new formats don't offer anything that's 10x better than current JPEGs, and you need a 10x improvement before consumers will adopt it.

There are some cool things about JPEG XR, but is it enough to supplant JPEG? No, probably not. Same reason why WMA/AAC/FLAC/whatever hasn't knocked out MP3 yet. MP3 is "good enough".

I'm glad to see that they're trying to get it accepted as an open standard (with full source code published). Proprietary formats suck.
