When the Photo CD format was designed in the early 1990s, a design goal was to allow low cost playback-to-TV devices. For example, a 16Base Photo CD image of 5.5 Mb can be encoded as a JPEG image of 2.1 Mb at 80% quality, visually indistinguishable from the original. In the consumer segment, the Photo CD format's relatively inefficient compression scheme meant that Photo CD files were significantly larger than JPEG files of similar quality, and thus less convenient for transmission across the internet, etc. However, by the late 1990s, Photo CD was being eclipsed by alternate formats, mainly based on the industry standard JPEG format. were active, with many more outside the U.S. īy 2000, over 140 Photo CD processing labs in the U.S. These measures, together with the then relatively low cost of $3 per image and convenience, made Photo CD the digital imaging solution of choice for many photographers in the mid to late 1990s. Bean in 1992 by which the catalog would be distributed in Photo CD format, and an arrangement with Silicon Graphics in 1993 to make all Silicon Graphics image-processing workstations capable of accepting Kodak Photo CD optical disks. This included, for example, an arrangement with L.L. Kodak entered into a number of partnerships in order to grow the usage of Photo CD. The project was expected to be a $600 million business by 1997 with $100 million in operational earnings. The first Photo CD products, including scanners for processing labs and Photo CD players for consumers, became available in 1992. Photo CD targeted a full range of photographic needs, ranging from consumer level point-and-shoot cameras to high-end professionals using large format 4x5 sheet film. The Photo CD system was announced by Kodak in 1990. History Photo CD player in the Photomusem of Zarautz (Spain) The Kodak Portfolio CD is not defined in any particular Rainbow Book. Some standalone Philips Photo/Audio CD players could play Portfolio CDs, and Windows player application was freely available. Separate from the Photo CD format is Kodak's proprietary "Portfolio CD" format, which combines Red Book CD audio and Beige Book PCD with interactive menus and hotspots on PCD images. This type is appropriate for 120 film, 4x5, but also for small picture film, if highest resolution is required. The Kodak Pro Photo CD Master Disc contains 25 images with maximum resolution of 6144 x 4096 pixels (six resolutions per file, Base/16 to 64 Base). Professional print, pre-press, archiving (optional) Both JPEG and JPEG 2000 support PhotoYCC colorspace as described below that is used in pcd files. Prior to Photo CD, professionals who wished to digitize their film images were forced to pay much higher fees to obtain drum scans of their film negatives and transparencies. The Photo CD system gained a fair level of acceptance among professional photographers due to the low cost of the high quality film scans. Their typical flicker became an issue when watching still photographs. However, these were designed for moving pictures. Furthermore, Photo CD relied on CRT-based TV sets for home use. The system failed to gain mass usage among consumers partly due to its proprietary nature, the rapidly decreasing scanner prices, and the lack of CD-ROM drives in most home personal computers of the day. They were intended to play on CD-i players, Photo CD players ( Apple's PowerCD for example), and any computer with a suitable software ( LaserSoft Imaging's SilverFast DC or HDR for example). Photo CDs are defined in the Beige Book and conform to the CD-ROM XA and CD-i Bridge specifications as well. Launched in 1991, the discs were designed to hold nearly 100 high quality images, scanned prints and slides using special proprietary encoding. Photo CD is a system designed by Kodak for digitizing and saving photos onto a CD.
