- Description
- Photo CD is a system designed by Kodak for digitizing and saving photos onto a CD. Launched in 1991 the discs were designed to hold nearly 100 high quality images, scanned prints and slides using special proprietary encoding.
- Group 4 (G4) used for black and white lossless compression to maintain high-quality images, commonly used in TIFF format compression by fax machines. A picture is seen as black dots and lines on a blank page; the fewer the dots and lines are, the lesser the file size.
