JPEG 2000

I have a lot of photos in JPEG, in fact the all are. I read up on JPEG2000 and realized that they would be better converted to this format, but how would I do this in Aperture? I don't see JPEG 2000 as an export option and all my images are in Aperture so I guess I would have to export them and batch save them as JPEG 2000 which sound quite arduous.

Any help with this?

MacBook, Mac OS X (10.5.1)

Actually is there anypoint in me converting my images to jp2 (JPEG 2000) if Aperture will not export them in that format, only conforming to JPEG. Unless I export the master?? but will that atach the metadata I added in Aperture?

It's not a very widely-supported format, so I wouldn't really recommend it.

But programs that can read jpg's can read jp2's .. Also its better, its lossless. Aperture should suppoert jp2, preview does for goodness sakes.

Really, I don't see the point. JPEG is really only suitable as a final, output format. And for there, it's ubiquitous.

JPEG 2000... I frankly have never seen it.

No they can't. JPEG2000 is a totally separate file format and support has to be added separately. Preview uses QuickTime's file parsing which can read almost anything. Even Photoshop needs an additional plug-in to read and write JPEG2000.

I didn't know that, I thought jp2 could be read by existing programs. But how long before my images degrade - its a bit like having botox before you need it, because when you freeze your face that's what you'll look like forever.. am I right in thinking that?

Also what does "final, output format" mean? how else woul you store an image in 'draft' format?
