Thanks for the suggestion.
I did look to IrfanView but it messes up the color space. Whatever the source's color space (mine are eciRGB v2), it outputs as sRGB. Photoshop keeps the color space intact but somehow fails to do lossless.
I would be cautious of jpeg 2000 as it is not widely accpeted and not everyone can open it. If doing this just for archival purposes storage is cheap today.
JPEG-2000 is not my personal preference, but my client wants it. Digitaal Erfgoed Nederland (http://www.den.nl/english) recommends uncompressed TIFF and lossless JPEG-2000 as archival formats. I only recommend uncompressed TIFF, but some clients insists on smaller files. (Which can add up when you got a couple of hundred thousand images to store.)
I still welcome any suggestions for a lossless, color space respecting, JPEG-2000 batch conversion solution.
You might check out the image processor at www.russellbrown.com/scripts.html. It is a lot more versatile than Bridge and while I have never used it may offer conversion to j-2000.
I use a utility called XnConvert - very poweful and free for non-commercial use. You can batch convert to amost any format you can dream up, including JPEG-2000 normal and JPEG-2000 file stream. It also has a companion application called XnView again free for non-commercial use and can open most file formats as well as do a bunch of other stuff.
I believe these programs are associated with some of the developers of Kolor Autopano Pro
Hope this helps
What version of photoshop and operating system are you using?
Thanks for all replies.
Curt, the Image Processor Pro from Russell Brown is a great tip. It offers more file formats to convert to than standard PS does, but unfortunately no JPEG-2000.
Mike, XnConvert is a nice tool, but doesn't do lossless JPEG-2000.
R_Kelly, I am using Photoshop CS5 and Windows 7 Pro 64bit.
Software I have tried so far: PS CS5, Reaconverter Pro 6.9, Chasys Draw IES Converter, IrfanView with LuraWave plug-in, XnConvert, FastStone Photo Resizer, Advanced Batch Converter. And I tried to use the LEADCommandLineutils from LeadTools, but couldn't get it to work.
You might try this j2k plugin for photoshop.
I think you'll have to remove the default JPEG2000.8BI plugin or photoshop will possibly get confused having two jpeg 2000 plugins.

Thank you very, very, VERY much! It works, both as "Save as" and recorded as Action and played back in a batch. The JPEG-2000 files are really lossless and kept their color space.
