摘要

This paper describes a family of 6.3 Megapixel digital cameras. The technology, features, and professional photography applications of these cameras will be presented. The family includes three different models, the Kodak Professional DCS 460 digital camera, the Kodak Professional EOS-DCS 1 digital camera, and the Kodak Professional DCS 465 digital camera back. The DCS 460 and EOS-DCS 1 cameras utilize Nikon N90s and Canon EOS 1 n professional 35 mm camera bodies, respectively. The DCS 465 camera back can be used with numerous medium and large format camera systems.The cameras are designed for portability and photographic versatility. The internal battery allows an average of 150 exposures per charge, and the battery can be recharged in as little as one hour. The PCMCIA interface is compatible with Type III-ATA removable disk drives. The integral SCSI interface allows quick connection and image download to a host computer. Voice annotation is provided for image documentation purposes. The DCS 460 and EOS-DCS 1 cameras are built on familiar professional 35 mm film camera bodies, and are compatible with the entire suite of lenses and other accessories offered by Nikon and Canon. The DCS 465 camera back incorporates a universal mounting system, developed by Eastman Kodak Company, which has been adopted by Hasselblad, Mamiya, Sinar, Toyo, and others.
