Pentax Electronic File
Pentax's native raw format, offering a choice against DNG.
PEF is the proprietary raw image format used by Pentax (Ricoh) cameras. Uniquely, Pentax DSLRs (like the K-1 and K-3) allow users to choose between saving files as PEF or Adobe DNG in-camera. PEF files contain the raw sensor data and proprietary metadata that is optimized for Pentax's own software.
PEF is a TIFF-based format using lossless compression. It is functionally very similar to DNG, but because it is proprietary, it may contain specific 'MakerNotes' that third-party software might not fully decode (though this is rare nowadays).
Pentax has used PEF since their first digital SLRs. Despite adopting DNG as an in-camera option, they have kept PEF as the default native format.
Wireless Bitmap
The pixel format of the Nokia 3310 era.
WBMP (Wireless Bitmap) is a monochrome graphics file format optimized for mobile computing devices using the Wireless Application Protocol (WAP). It was designed for the extremely limited bandwidth and display capabilities of early 2000s feature phones.
A WBMP file is an uncompressed sequence of bits with a minimal variable-byte integer header usually encoding generic type (0), width, and height. It supports only 1-bit color (black and white). There is no compression, palette, or gray scale.
Developed by the WAP Forum to deliver icons and simple graphics to mobile phones over 2G networks.
