new JPEG Standard 9.1: Supports 12-bit colour depth and lossless compression

PetaPixel report. This could be an alternative to TIFFs and proprietary RAW formats - with the advantage over Adobe's DNG, Canikon and others that it will not be dependent on continuing support from one corporation. I'm guessing JPEGs would be more likely readable by a wider variety of devices than TIFF files.

Anything that democratises storage and access to uncompressed image files is a good thing, to my way of thinking. Of course it will need device manufacturer support, something they may be reluctant to do.

... along with a massive amount of software support.

so, what does this all mean, how would it work?
would it be for only new cameras, can it be a software upgrade in our old/current cameras?

More readable than Tiff sorry but there is a reason why tiff is considered the archival image standard something that jpeg will never truly be. Completely losless compression is a myth the advantage of tiff is that it's readable even if the file is corrupted any form of compression will make the file unreadable if corrupted that's Tiff advantage over any other image file format.

It means that your Jpegs will be coded on 2x2x2x2x2x2x2x2x2x2x2x2 levels per each color channel instead of 2x2x2x2x2x2x2x2 levels per each color channel.

And without compression.

So you have more color and greyscale depth, and less pixels destruction.

Remember JPEG 2000?

No doubt this will prove to be just as amazingly popular...

You are most likely correct. Like JPEG2000, this new spec seems like a solution in need of a problem.

In my opinion, and it's just my opinion, Jpeg is as popular as it is because it's less complicated, not more. It's readable by devices and programs than most other formats. There are formats which hold more information and formats which hold less. But nearly anything that can display an image can display a standard Jpeg. You can print from it, you can edit it, you can show it on your cell phone or a 4k TV. It's limited in what it can do, but it can show an image that looks like an image. No more, no less.
