Convert ERF to RAD

The ERF file extension, short for Epson Raw File, is a proprietary format used by Epson digital cameras to store uncompressed, raw image data. Developed by Epson, this format retains all original sensor data, allowing photographers to produce high-quality images with extensive post-processing flexibility. ERF files can be opened and edited using specialized software like Adobe Photoshop and Epson PhotoRAW. Despite their large size, ERF files are favored by professionals for their superior image quality and editing capabilities.

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.
