About formats

SR2 is an early proprietary RAW image format used by Sony for select digital camera models, most notably the Cyber-shot DSC-R1 released in 2005 — a unique fixed-lens camera featuring a large APS-C CMOS sensor that was Sony's first to use this sensor size in a compact body. SR2 files capture the unprocessed 12-bit readout from the camera's sensor in its native Bayer mosaic pattern, preserving the full dynamic range and color information before any demosaicing, white balance adjustment, or tonal processing. The format uses a TIFF-based container structure with Sony-specific metadata tags and lossless compression to keep file sizes manageable while maintaining bit-perfect sensor data preservation. SR2 represents a transitional format in Sony's imaging history: it succeeded the earlier SRF format and preceded the ARW format that would become Sony's standard RAW format across the Alpha mirrorless and DSLR lineup from 2006 onward. The DSC-R1's APS-C sensor paired with a fixed Carl Zeiss Vario-Sonnar zoom lens made it an unusual proposition — essentially a compact camera with DSLR-class image quality — and SR2 files from this camera are valued by collectors. One advantage is the preservation of data from a unique camera design: the DSC-R1's combination of large sensor and fixed optics produced a distinct imaging character, and SR2 files retain the full RAW flexibility to explore this character with modern processing tools. SR2 files are supported by Adobe Lightroom, Adobe Camera Raw, dcraw, LibRaw, and RawTherapee.

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.
