HD Photo to become JPEG XR

HD Photo to become JPEG XR | Underexposed – CNET News.com

From Stephen Shankland over at CNET:

“A new attempt to provide a higher-end sequel to the ubiquitous JPEG image standard is officially under way.

The multiple countries participating in the Joint Photographic Experts Group, which created the JPEG standard, have approved an effort to make Microsoft’s HD Photo format a standard called JPEG XR, said Bill Crow, who has led Microsoft’s HD Photo effort and who just took over the company’s Microsoft Live Labs Seadragon imaging project. XR stands for “extended range,” a reference to the format’s ability to show a wider and finer range of tonal gradations and a richer color palette.

“The country vote is done, and it passed,” Crow said. “That means the International JPEG committee has decided to go ahead and create the standard. Now it’s just a process of doing that work,” a process that will begin later this month in a meeting in Kobe, Japan.

The move is an important step in the transformation of the photo format from an in-house technology called Windows Media Photo to a neutral format more likely to be palatable to companies that don’t want to be beholden to Microsoft.”

    For this new standard to be successful, it needs to be truly open and free. That means that no one owns it, it has to be completely open source, Microsoft should have not strings attached to it, no company can have a patent covering the technology, no one will have any right to collect royalties on it’s usage. If the new standard is not totally free and open, there is little chance that camera manufacturers and photo editing software developers will support it.

    The new file format will need to have the following features to be of use to serious photographers.
    1) Must be able to save the image data in a 16 bit format.
    2) Should have the ability to save HD image data in at least a 32 bit format. This might allow a camera to take two or more frames at different exposures and then combine them into a a single HDR file inside the camera.
    3) Will need a lossless compression option.
    4) Will need to have an option to retain the image data captured by the sensor without any in camera processing, sort of like a RAW or Adobe’s DNG file format, but packaged and compressed into the new file format.
    5) It will need to support a color space wider that sRGB, such as AdobeRGB or ProPhotoRGB.

    From what I have read, the new jpg XR file format will address most if not all of the items I listed above. Let’s hope that if this is truly a viable replacement for the existing jpg format, that it does not end up a dead end like jpeg2000.

    Wasn’t PNG going to be the new jpg?
