Sony Alpha RAW
The raw format powering the mirrorless revolution.
ARW is the raw image format used by Sony's Alpha series cameras (like the A7, A6000, and ZV series) and Cyber-shot RX series. As Sony became the dominant player in the mirrorless camera market, ARW became one of the most common raw formats in the world. ARW files contain the raw data from Sony's Exmor sensors. They are known for their malleability, allowing photographers to push shadows and pull highlights to extreme degrees without the image breaking apart.
ARW files are TIFF-based containers. Sony offers three main compression types: 1. **Uncompressed**: Massive files, but guaranteed maximum data integrity. 2. **Compressed (Lossy)**: The default for years. It uses a delta-compression scheme that can occasionally cause 'star eater' artifacts or posterization around high-contrast edges, but saves 50% space. 3. **Lossless Compressed**: Introduced in newer models (A7 IV, A1) to solve the quality issues of lossy compression without the massive size of uncompressed.
ARW replaced the older SR2 format. It has gone through several iterations (v2.3, v4.0). The format faced controversy in the past due to its lossy compression algorithm, which led Sony to introduce the Uncompressed and later Lossless Compressed options in response to user demand.
DPX (Digital Picture Exchange)
The industry standard for digital intermediate and visual effects work in film.
Digital Picture Exchange (DPX) is a raster image format used primarily in the motion picture industry for visual effects (VFX) and Digital Intermediate (DI) work. It is an ANSI/SMPTE standard (SMPTE 268M-2003) designed to represent the density of film scans without loss of quality. Unlike consumer formats, DPX is usually uncompressed and stores color information in a 'logarithmic' (Log) format to preserve the full dynamic range of motion picture film. A single second of 4K movie footage in DPX format can consume enormous amounts of storage (hundreds of megabytes), making it strictly a production format, not one for distribution.
A DPX file starts with a 'Generic Image Header' (magic number: SDPX) containing core details like file size and image orientation. This is followed by 'Industry Specific Headers' for Motion Picture or Television data (timecodes, frame rates). Finally, the 'Image Data' block contains the raw pixel values. DPX supports a wide variety of bit depths, but 10-bit Log RGB is the most common industry standard. It packs these 10-bit values tightly into 32-bit words (10+10+10+2 padding) for efficient processing. The logarithmic encoding mimics the human eye's response to light and the physical characteristics of film stock.
DPX is the direct successor to Kodak's Cineon (.cin) format, which was developed in the early 1990s for the first digital film scanners. As the industry moved towards digital workflows, SMPTE (Society of Motion Picture and Television Engineers) standardized Cineon into DPX to ensure compatibility between different vendors' scanners, printers, and software.
