Seattle FilmWorks Image (.sfw)

The SFW file extension stands for Seattle FilmWorks Image, a proprietary bitmap image format created by Seattle FilmWorks, a company specializing in film processing and digital imaging. Although the company is now defunct, SFW files can still be viewed using specific software or converted to standard formats like JPEG. This format is not widely supported by modern image editing software.

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.
