Convert RAD to PSB

The RAD file extension, associated with the Radiance software suite, stands for Radiance Scene Description. It is used to describe materials and geometry for lighting simulations and rendering programs. Developed by Greg Ward at Lawrence Berkeley National Laboratory, Radiance employs ray tracing and an octree data structure for accurate lighting calculations. RAD files are ASCII text files that must be compiled into an octree before rendering.

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.
