Retaining Color Fidelity in Photo CD Image Migration

The Photo CD system, originally aimed at consumers, has also been used by cultural institutions to store digital images from scanned photographic film, prints, and documents. With improvements in technology and anticipated adoption of new digital image standards, e.g., JPEG 2000, retention of image fidelity during migration of digital collections is often a concern. In a previous report (Archiving Conf. 2005), we described the format and colorimetric definition of images stored on Photo CD disks. Here we address several steps that can be taken to ensure the retention of the original subject color information, and the straightforward display and exchange of derivative images. The rationale and practical considerations for using embedded ICC color profiles will also be discussed.
