Convert PSB to CALS

The PSB (Photoshop Large Document Format) file extension is utilized for handling exceptionally large images in Adobe Photoshop. Introduced to support projects exceeding the limitations of the traditional PSD format, PSB is optimized for files that surpass 30,000 by 30,000 pixels, accommodating up to 300,000 pixels in either dimension. This format is essential for professional photographers, graphic designers, and digital artists who work with high-resolution images, providing a robust solution for maintaining the integrity and quality of detailed visuals in complex projects. PSB's development has been integral to Adobe's efforts to enhance the capacity and efficiency of its image editing software, ensuring that professionals can work without restrictions on image size and complexity.

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.
