About formats

CRW is Canon's first-generation RAW image format, based on the Camera Image File Format (CIFF) specification developed jointly by Canon, Kodak, and other imaging companies in the late 1990s. Used by Canon's consumer and prosumer cameras from approximately 1998 through the early 2000s — including the PowerShot G-series, EOS D30, EOS D60, and EOS 10D — CRW files store the unprocessed 12-bit sensor readout in a heap-based container structure that differs fundamentally from the TIFF-derived approach used by most other camera manufacturers. The CIFF container organizes data into a hierarchical directory of heap entries, each identified by type and tag, containing the raw image data, JPEG thumbnail, EXIF information, and Canon's proprietary metadata including White Balance tables and Picture Style parameters. CRW was eventually replaced by the CR2 format starting with the EOS-1D Mark II in 2004, as Canon moved to a TIFF-based container that aligned more closely with industry conventions and supported higher bit depths. One advantage of CRW files is historical completeness: they preserve the full original sensor data from an important transitional period in digital photography, and the 12-bit captures from cameras like the EOS D30 still produce excellent results when reprocessed with modern RAW converters. Broad legacy support is another strength — despite its age, CRW remains readable by Adobe Lightroom, Photoshop, RawTherapee, and other modern converters, ensuring these early digital negatives remain accessible.

PICON (Personal Icon) is a small-format image type used in the X Window System ecosystem, developed by Steve Kinzler at Indiana University around 1990 as part of the picons (personal icons) database project. Picons are small, typically 48x48 pixel, color images used as visual identifiers for people, organizations, domains, and Usenet newsgroups in Unix mail readers, news readers, and other communication tools. The picon format is essentially an XPM (X PixMap) image stored with specific naming conventions and directory structures that allow software to look up the appropriate icon based on email address, domain name, or newsgroup name. The picons database organized thousands of these small images in a hierarchical directory structure keyed by domain name components (e.g., faces/com/example/user.xpm), enabling mail clients like exmstrstrstr and faces to automatically display a sender's photo or organizational logo alongside their messages. The system predated the modern concept of contact photos and avatars by more than a decade. One advantage is the system's pioneering role in visual identity for electronic communication: picons introduced the idea that email and Usenet messages should display a visual representation of the sender — a concept that eventually became standard in every modern email client, messaging app, and social media platform. The XPM-based format ensures that picons are displayable on any system with X Window libraries. Picon images are supported by ImageMagick, GIMP, and X Window display utilities, and the historical picons database remains archived online at Indiana University.
