Photo CD Multi-resolution Bitmap Graphics (.pcds)

The PCDS file extension stands for Photo CD Multi-resolution Bitmap Graphics, a format developed by Kodak in 1991 for digitizing and storing high-quality images on CDs. PCDS files were used to store scanned prints and slides, leveraging proprietary encoding to maintain image quality. This format was part of Kodak's Photo CD system, which aimed to provide a reliable method for archiving and accessing digital photographs.

Continuous Acquisition and Life-cycle Support Type 1 Image (.cals)

The CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image file format, developed by the United States Department of Defense in the mid-1980s, is a standard for storing raster (bit-mapped) image data, typically black-and-white. It ensures efficient data interchange and retention of orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images. This standard was part of the broader CALS initiative aimed at improving electronic publishing and data management within the federal government.
