There has been new cameras everyday, but the file formats that the cameras have been using since last decade have not been changed at all. I have been reading some articles about the new proposed JPEG XR format (HD JPEG). It's said to be more efficient while yields better image quality.


However, by now I'm still confused by how it works technically; I'm not sure about what exactly is the benefit we will get from it in terms of image quality rather than just knowing that it's going to be "better". If such a format has a clear advantage, then how come the cameras now are still using the standard JPEG? Is it just a time issue or is there something that is difficult to implement? I can imagine it's hard to set a new standard format when an existing format has already been widely used as the standard. Can anyone who's knowledgeable enough to know about this explain?


I'm here to learn from you.[]
