JPEG XR Support for Camera
Make JPEG XR format an option for the camera output.
Here's a good way Jpeg-XR could be used:
Have a Jpeg XR lens option. Or something similar, let me explain..
When you take a photo a Jpeg version that photo is stored in your camera roll. This has the advantage of being openable everywhere by all software. At the same time a Jpeg XR image is stored as a rich media object tied to that photo. The Jpeg XR image stores 12 bits per channel (most smartphone cameras will provide 12 bits per channel, but only 8 bits get used ever because that's all jpeg supports) which allows it to be use to adjust the image exposure and other settings after taking the photo without causing banding or other artefacts of image degradation.
I don't see this kind of thing done on any other smartphone today and it seems like it could be a real win for anyone who could be first to do it.

I've just noticed that JPEG XR can be viewed on the phone (WP8 at least -- not sure about WP7).
But, why isn't it an option as an output???
I agree with Tim
Somebody really needs to break the ice on a format that's better than JPEG and doesn't have the overhead of RAW. It’s stunning that actual camera manufacturers haven’t yet picked up the JPEG XR format and it would be great if Microsoft takes another step to help push forward a better format that they developed; perhaps making it as part of minimum WP7(8) specs. Naturally it would be expected that the phone would have to support JPEG as well since JPEG is such an entrenched format. As the megapixels increase in WP7 phones, being able to say that you capture a fuller range of color over non-JPEG XR capable smartphones can be a differentiator in favor for Windows Phones.
I'd like to see jpeg-xr supported in the application framework too. I've run into one or two situations were I would have liked to have a image format that supported lossy compression and transparency.
As the company that introduced HD Photo, it would make sense for Microsoft to bring JPEG XR to devices -- especially WP7 since it has a camera.
