Convert K25 to RAD

The K25 file extension stands for Kodak DC25 Digital Camera Raw Image. It is a proprietary format used by the Kodak DC25 digital camera, introduced in the mid-1990s. K25 files store unprocessed image data directly from the camera's sensor, preserving high image quality and allowing extensive post-processing. This format was pivotal in early digital photography, enabling users to manipulate images without significant quality loss.

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.
