The X3F file extension, created by Sigma Corporation for its digital cameras with Foveon X3 sensors, captures raw image data with superior color accuracy and detail. It includes metadata and preview images, making it ideal for professional photographers. Sigma provides Sigma Photo Pro software for managing these files, and plugins are available for popular photo editing software. Despite limited support compared to other raw formats, the X3F format is highly valued by Sigma camera users for its exceptional image quality.
The CAL file extension, known as CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image, is a 1-bit black-and-white raster image format developed by the U.S. Department of Defense in the mid-1980s to standardize graphics data interchange for military documentation. It is primarily used for storing and sharing monochrome images while retaining orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images.
