Canon RAW 3
The modern, efficient raw format for Canon's mirrorless era.
CR3 is the current raw image format used by Canon's EOS R mirrorless cameras and newer DSLRs. Introduced in 2018 with the EOS M50, it completely replaces the older CR2 format. The biggest innovation in CR3 is the introduction of 'C-RAW' (Compact Raw). This is a lossy compression option that reduces file sizes by up to 40% with virtually no visible loss in image quality. This allows photographers to shoot longer bursts, save hard drive space, and transfer files faster without sacrificing the flexibility of raw editing.
Unlike CR2, which was based on TIFF, CR3 is based on the CIFF (Camera Image File Format) structure, which is related to the MP4 container. This modern architecture allows for faster reading/writing and better metadata handling. CR3 files store 14-bit sensor data. In standard mode, it uses lossless compression. In C-RAW mode, it uses a smart lossy algorithm that prioritizes highlight and shadow detail while compressing midtones.
As sensor resolutions jumped from 20MP to 45MP+ (like in the EOS R5), file sizes became unmanageable. CR2 files were getting too big. Canon developed CR3 to solve this storage bottleneck, launching it alongside their push into full-frame mirrorless cameras.
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.
