I'm both a serious photographer and a reporter who's written about image formats and digital photography hardware and software. I see it as extremely unlikely that camera makers will abandon raw formats for their higher-end models. Although newer formats such as JPEG XR offer some potential benefits regarding color gamut, compression, and bit depth when compared to conventional JPEG, raw photo formats (and Adobe's DNG format, which it's trying to standardize) retain flexibility that JPEG XR necessarily loses. For example, when creating a JPEG or JPEG XR or WebP image from the raw sensor data, a camera makes irrevocable decisions about white balance, noise reduction, and sharpening. Photography pros and enthusiasts value this flexibility and aren't likely to be happy to see it go away. It's possible that JPEG XR could catch on as an alternative to JPEG. However, I haven't detected enthusiasm among camera makers, who've had several years to embrace JPEG XR if they wanted to, and I don't see Microsoft or others trying to advocate adoption in hardware. If camera makers don't support JPEG XR, there's much less of an incentive to support it on the Web since ordinary people won't be uploading their photos with it. There might be some advantages in compression ratio and alpha channel for Web developers and graphic artists, of course, but at least for the foreseeable future I don't see this as a mainstream graphics format. _______________________________________________ dev-platform mailing list [email protected] https://lists.mozilla.org/listinfo/dev-platform
