Sony RAW 2
The predecessor to the modern ARW format.
SR2 is an older raw image format used by early Sony digital cameras, particularly the Cyber-shot R1 and early DSLRs before the Alpha branding fully took over with the ARW format. It contains raw sensor data, allowing for the same kind of editing flexibility as modern raw files, but from older sensor technology.
SR2 is a TIFF-based format. It typically stores 12-bit data. The encryption used in SR2 files was a point of contention in the early days of open-source raw decoding.
Sony used SRF, then SR2, and finally settled on ARW. SR2 represents the middle child of this evolution.
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.
