Minolta RAW
The raw format of the Konica Minolta era.
MRW is the raw image format used by Minolta and Konica Minolta digital cameras (like the DiMAGE series and the Maxxum/Dynax 7D) before the camera division was sold to Sony in 2006. MRW files contain the raw sensor data from these early DSLRs and bridge cameras.
MRW files are not TIFF-based; they use a proprietary structure. They typically store 12-bit sensor data.
Minolta was an innovator (first IBIS in a DSLR). When Sony bought them, they used the technology to build the Alpha system. The MRW format was replaced by Sony's ARW.
JPEG 2000 File Format
The advanced successor to JPEG that never quite took off on the web.
JPEG 2000 (JP2) is an image compression standard and coding system. It was created by the Joint Photographic Experts Group committee in 2000 with the intention of superseding their original discrete cosine transform-based JPEG standard with a newly designed, wavelet-based method.
JP2 uses discrete wavelet transform (DWT) technology, which allows for higher compression ratios without the 'blocky' artifacts seen in standard JPEGs. It supports both lossy and lossless compression in a single architecture and allows for progressive decoding (quality or resolution).
Released in 2000 as a modern upgrade to JPEG. Despite its technical superiority, it failed to gain widespread web adoption due to patent concerns, complexity, and the 'good enough' nature of standard JPEG.
