Why sRGB?
If JPEG 2000 is meant to be "powerful for both print and Web publishing," why use sRGB as the standard? That's fine for the Web, at least in its current state, but a poor, limited-gamut choice for print.
JPEG 2000 is good but
I agree with MortenH. 8-bit alphachannels 0wn j00, and jpeg 2000 really needs to have them. Transparency is VERY important!
Compatibility
Thanks for an informative and well written article.some info on support and compatibility would have been good though, i.e. when can we expect browsers, image editing and layout software to start supporting jpeg 2000?
something about history...
hello together,
as a reader from germany i am a little concerned about the subheadline "JPG über alles" in this article. i wonder if you know, that this phrase from the german national anthem was abused by the national socialists and adolf hitlers government in the 1930s. so i think it would be better to be carful when using "slogans" like this if you don't really know where they are from.
best regards, felix kautzsch, frankfurt/germany
JPEG2000 good in some fields...
I agree that the old JPEG format has had its time. Better compression with less artefacts is better, as long as it is used in fields where compression is important. That would be web. These days storage is for the masses. Internet broadband connectivity isn't. I work in a design company, and sure, we use comping images from web based image providers. We can download their images and decompress them into tiff. Good. JPEG 2000 makes sense there. Webdesign as well. (They should have JPEG2000 support for the browsers first, creation tools later).
I do not agree with the post from MortenH. A new image format with 8-bit alphachannels is really not needed in the aforementioned fields. That should be a new kind of EPS, and dtp programs should also support it. It would be great to have an image with partial transparency or a dropshadow (vector- or bitmap based) and place it anywhere on top of anything in InDesign or Quark... just dreaming there kids...

sRGB not so great
I'm disappointed that this new version of JPEG will be standardized to sRGB. This is a limited version of RGB with a much narrower color gamut. It's a very short-sighted decision. Today sRGB makes sense, especially since low-cost business systems can't handle a wider gamut of color. But better quality monitors will be the norm by the time the new JPEG format will actually be widely supported, so we're actually creating a new standard that is obsolete before it gets a fighting chance.
Where's my alpha channel?
If there's one thing that would change the graphical web as we know it it would be 8 bit alphachannels, or advanced transparancy. To see that possibly the only new image format with a chance of becoming a new standard (PNG implementations are poor for the moment at least), doesn't include this functionality, is sad indeed.
