About formats

MRW is the proprietary RAW image format developed by Minolta (later Konica Minolta) for their digital SLR and advanced compact cameras, introduced in 2001 with the DiMAGE 7, one of the first consumer-grade digital cameras to offer RAW capture alongside JPEG. MRW files capture the unprocessed 12-bit readout from the camera's CCD sensor in its native Bayer mosaic pattern, storing the data in a container format with a series of tagged data blocks for the raw image, camera settings, and proprietary metadata. The format was used across Minolta's digital camera lineup including the DiMAGE A-series advanced compacts and the Dynax/Maxxum 5D and 7D digital SLRs — the latter being the first DSLRs with built-in sensor-shift image stabilization, a technology later inherited by Sony when they acquired Konica Minolta's camera division in 2006. MRW files preserve the original sensor values needed for high-quality demosaicing, custom white balance, and exposure adjustment, giving photographers flexibility unavailable with the camera's in-body JPEG processing. One advantage is historical technological significance: MRW files from the Dynax 7D and its predecessors document the pioneering implementation of in-body stabilization and other innovations that became industry standards, and the RAW data preserves these early captures in their most flexible form. Continued compatibility is another strength — MRW files are supported by Adobe Lightroom, dcraw, LibRaw, RawTherapee, and other modern RAW converters, keeping these Minolta-era digital negatives fully usable with current processing algorithms.

HRZ is a simple raster image format associated with slow-scan television (SSTV), a method of transmitting still images over radio frequencies used by amateur radio operators since the late 1950s when Copthorne Macdonald pioneered the technology. HRZ files store images at a fixed resolution of 256x240 pixels in raw RGB format, with each pixel represented as three bytes (red, green, blue) at 8 bits per channel, producing uncompressed files of exactly 184,320 bytes. The format has no header, no metadata, and no compression — the file is simply a sequential dump of raw pixel data in row-major order. This extreme simplicity reflects the format's origins in the amateur radio community, where SSTV images are transmitted as audio tones encoding luminance and chrominance values over narrow-bandwidth HF (shortwave) radio channels. The fixed 256x240 resolution corresponds to common SSTV transmission modes, and HRZ files serve as the digital capture or storage medium for received SSTV transmissions. One advantage is the format's zero-overhead structure: with no parsing, decompression, or metadata processing required, HRZ files can be read by any program capable of reading raw pixel data with known dimensions — a single function call in virtually any programming language. The format's connection to amateur radio SSTV culture is another notable aspect: HRZ files document a unique form of image communication where operators transmit photographs over thousands of miles using nothing but radio waves and audio encoding, a practice that continues today alongside digital modes. HRZ files can be opened by ImageMagick, GIMP, and specialized SSTV software.
