You might want to read the following article where the authors decided not to use JPEG2000 for their project for several reason. Here are three of them: 1. JPEG2000 does not preserve the TIFF technical metadata when converted to JPEG2000 2. JPEG2000 files are more inconvenient to OCR than TIFF 3. JPEG2000 has no browser support yet From TIFF to JPEG 2000?

The digital online catalog project Connecticut History Online (www.cthistoryonline.org) used jp2s for phase 2 of their project to allow both zooming in on large images (like maps and bird's-eye views), and save space on the server. (It is a collaborative project, so individual institutions are responsible for their own archival images - here at CHS we archive in TIFF currently.) Not all of the images on the site are jp2s, just the 'oversize' items, but the ones that I have used and seen, work very well.

The UK's Wellcome Library announced they were using JPEG2000 last year - they've blogged about it at http://wellcomelibrary.blogspot.com/2009/09/wellcome-library-to-use-jpeg2000-image.html. The page also includes a copy of the report that informed their decision, or you can download it directly at http://library.wellcome.ac.uk/assets/wtx056572.pdf I'd be interested to hear what you decide to do - JPEG2000 looks interesting for its ability to offer deep zooming for publication online but it's hard to get a sense of how widely it's supported or used. cheers, Mia http://openobjects.org.uk/ http://twitter.com/mia_out

Hi Perian, Before making a major commitment to JP2000, you might consider converting those NEF's to DNG, which remains (so far as I am aware - and I expect others to jump in momentarily) more widely implemented than JP2000.

I think right now JPEG2000 is more a specialized tool, some web software use it to allow you to zoom in without getting the whole big file. Unless you download multiple sections and stitch them back together. But I digress. I think right now I would still use tiff or some raw format dng or nef as my master file.
