Minolta RD-175 RAW
A multi-sensor raw format from the 90s.
MDC is the raw format used by the Minolta RD-175, a DSLR released in 1995. The camera was unique because it used *three* separate CCD sensors to create a single image, similar to 3CCD camcorders.
The RD-175 used three 0.38 megapixel sensors. Two sensors captured green and one captured red/blue. The MDC file stores this split data, which must be interpolated to form the final 1.75 megapixel image.
One of the first portable DSLRs.
JPEG 2000 VM Uncompressed
A single-component test format for JPEG 2000 verification.
PGX is an extremely simple, uncompressed raster format created specifically for the development and testing of the JPEG 2000 standard (ISO 15444). It is defined in the JPEG 2000 Verification Model (VM). Its purpose is to store a single component (channel) of an image with potentially high bit depth and signed/unsigned values, without the complexity of a full image container.
A PGX file represents one image channel (grayscale). It starts with a minimalist text header identifying the endianness (`LMS` or `Big`), the sign (`+`/`-`), the bit depth, and dimensions. The raw pixel data follows immediately. It is effectively a raw dump of a single image plane.
Developed by the JPEG committee during the creation of JPEG 2000. It allowed researchers to test wavelet compression algorithms on raw data without worrying about file headers or color transforms.
