JPEG 2000 Produces images with better compression, quality, color management, and metadata capability than
JPEG. JPEG 2000 also supports transparency in layered images and retains any saved selections. Photoshop Elements
saves images in extended JPEG 2000 (JPX) format, which is a more comprehensive file format than standard JPEG
2000 (JP2). You can make files JP2 compatible by selecting an option in the JPEG 2000 dialog box. (See "To save a
file in JPEG 2000 format" on page 69.)
The standard Photoshop Elements format. You should generally use this format to save your work
