To save a file in JPEG 2000 format (optional Photoshop plug-in)
To save files in the JPEG 2000 format, you must get the optional JPEG 2000 plug-in and install it in this location:
Adobe Photoshop CS2/Plug-Ins/Adobe Photoshop Only/File Formats. This plug-in is available on the Photoshop
CS2 installation CD in Goodies/Optional Plug-Ins/Photoshop Only/File Formats. Extended JPEG 2000 (JPF) format
provides an expanded set of options compared to the standard JPEG 2000 (JP2) format. However, you can make files
JP2 compatible by selecting the appropriate option in the JPEG 2000 dialog box.

Note: If you want to save a JP2-compatible file, you must select the ICC Profile option (Windows) or the Embed Color
Profile option (Mac OS) in the Save As dialog box. Otherwise, the JP2 Compatible option will be unavailable in the JPEG
2000 dialog box. The JP2-compatible option slightly increases the JPF file size. Keep in mind that JP2 viewers are not
required to support ICC profiles and metadata present in JPF files, so color fidelity and other features may not work as
expected.
