HD Photo, JPEG, JPEG 2000
This comparison shows how well JPEG, JPEG 2000 and Microsoft's HD Photo (formerly called Windows Media Photo) compress the upper-left image.
The more colors that show, the more the compressed version varies from the original--so a perfect job would be completely black. Each compressed image is one-eighth the file size of the original.
