About formats

CR2 (Canon RAW version 2) is Canon's second-generation proprietary RAW image format, introduced in 2004 with the EOS-1D Mark II and used across Canon's DSLR lineup until the transition to CR3 beginning in 2018. CR2 files use a TIFF-based container that stores the raw sensor data compressed with a lossless variant of JPEG encoding (Huffman-coded prediction residuals), keeping file sizes manageable while preserving every bit of the original capture. Each CR2 file contains multiple image sections: a small thumbnail, a mid-size preview JPEG suitable for quick review, and the full-resolution RAW data at 14-bit depth on most bodies. The format records extensive shooting metadata including Canon's proprietary tags for lens model, autofocus point selection, Picture Style settings, dust-delete data from the sensor cleaning reference shot, and per-body calibration information. One advantage is the vast software ecosystem — CR2 is one of the most widely supported RAW formats in existence, handled natively by Adobe Lightroom, Capture One, DxO, RawTherapee, darktable, and dozens of other converters and viewers, owing to Canon's dominant market share during the DSLR era. Reliable archival longevity is another key strength: the TIFF-based structure and well-documented layout make CR2 files relatively straightforward to parse even with custom tools, and the format's ubiquity means archival support will persist for decades.

Initial release: 2004
SK is the native file format of Skencil (originally named Sketch), a free vector graphics editor for Linux created by Bernhard Herzog, with the first public release on October 31, 1998. Skencil holds historical significance as one of the earliest full-featured vector drawing applications written almost entirely in Python, with only performance-critical rendering components implemented in C. The SK file format uses a text-based, Python-like syntax to describe document structure — pages, layers, groups, and individual graphic objects are represented as nested statements with parameters specifying coordinates, colors, line styles, and transformations. The format supports Bezier curves, rectangles, ellipses, text objects with font specifications, imported raster images, gradient and pattern fills, and hierarchical grouping with affine transforms. One advantage is human readability — SK files can be opened in any text editor, making it possible to inspect, modify, or generate artwork programmatically using simple scripts. The Python-native structure also provides a benefit for automation: since Skencil itself is a Python application, the file format integrates naturally with scripting workflows for batch processing and procedural graphic generation. While Skencil's development slowed after the mid-2000s, its SK format became the foundation for the sK1) project, which extended the format and continued active open-source vector graphics development. SK files remain convertible through sK1, UniConvertor, and other open-source tools.
