Would that help: Photoshop Camera Raw & JPEG 2000?
I was eagerly searching a solution to my problem when I found adobe's Photoshop Camera Raw & JPEG 2000 downloadable plug in which helps photoshop reading RAW.
Do you think it is something we need to resolve the RAW question?
All I would like to achieve is to shoot in RAW, but not to convert it to tiff, because the process takes lots of time and would be unnecessery if something would be able to use RAW. I just don't really know if it is really what i need, I thought you might know more about this plugin.
