Radiance HDR (.hdr)

HDR stands for High Dynamic Range, and in the context of Radiance, it refers to a file format used for storing high-quality images. The Radiance HDR format was developed as part of the Radiance rendering system, which originated in the late 1980s at the Lawrence Berkeley National Laboratory. Its primary use is in the field of computer graphics, where it captures a wider range of luminance levels compared to standard formats, enabling more realistic lighting effects. This format is particularly beneficial for tasks requiring precise light measurements and accurate visualizations, making it indispensable for professionals in fields such as architectural visualization and visual effects.

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.
