Convert SR2 to CALS

The SR2 file extension stands for "Sony RAW 2", a format used by Sony digital cameras to store uncompressed image data. Introduced in December 2005 with the Sony DSC-R1 model, SR2 files capture raw image data directly from the camera's sensor, preserving maximum detail and dynamic range for post-processing. This format is favored by professional photographers for its flexibility in editing and superior image quality compared to compressed formats. SR2 is part of Sony's suite of RAW formats, which also includes SRF and ARW.

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.
