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.
Picture Exchange
The de facto standard for DOS paint programs.
PCX (Picture Exchange) was one of the first widely accepted standards for DOS imaging. Created by ZSoft for their PC Paintbrush software, it became the native format for Windows 3.0 Paintbrush and supported the evolution of PC graphics hardware from monochrome CGA to 256-color VGA and eventually 24-bit TrueColor.
PCX uses a header containing the version, dimensions, and palette information, followed by image data compressed using a simple Run-Length Encoding (RLE) scheme. This scheme was very efficient for the simple graphics of the 80s (large areas of flat color) but is poor for complex photographs. 256-color palettes are often appended at the end of the file.
Established in 1985. It enjoyed a decade of dominance before being displaced by BMP (on Windows), GIF (on the web), and JPEG (for photos). It is now largely obsolete but still recognized by many tools due to its historical significance.
