About formats

NRW is a variant of Nikon's RAW image format used specifically by their COOLPIX advanced compact cameras, introduced in 2008 with models like the COOLPIX P6000. While functionally similar to NEF (Nikon Electronic Format) in preserving unprocessed sensor data, NRW uses a simplified container structure tailored to the compact camera platform's processing constraints and smaller sensor sizes. NRW files store 12-bit raw Bayer-pattern data from the camera's smaller-format CMOS or CCD sensor, along with embedded JPEG thumbnails, basic EXIF metadata, and a subset of Nikon's MakerNote information. The format was designed for the COOLPIX cameras that bridged the gap between consumer point-and-shoots and interchangeable-lens systems — cameras like the P7000/P7100/P7700/P7800 series and the P330/P340 that attracted enthusiasts wanting RAW flexibility in a pocketable body. Unlike the full NEF format, NRW files typically use a fixed compression scheme and omit some of the more extensive metadata found in NEF files from Nikon's SLR and mirrorless bodies. One advantage is that NRW provides genuine RAW capture flexibility in compact camera form factors where most competitors offered only JPEG — photographers can apply custom white balance, adjust exposure, and control noise reduction during post-processing rather than relying on the camera's built-in processing. Software compatibility is another strength: NRW files are supported by Adobe Lightroom, Adobe Camera Raw, Nikon's ViewNX/NX Studio, dcraw, and other major RAW processors.
Developer: Nikon
Initial release: 2008
WBMP (Wireless Bitmap) is a monochrome (1-bit, black and white) image format defined as part of the Wireless Application Protocol (WAP) specification, developed by the WAP Forum (later consolidated into the Open Mobile Alliance) around 1998. The format was designed for the extremely constrained mobile devices of the late 1990s and early 2000s — phones with small monochrome screens, minimal processing power, and narrow bandwidth GSM data connections. WBMP uses the simplest possible encoding: a type identifier byte (always 0 for the only defined type), width and height encoded as multi-byte integers using a variable-length scheme, and the raw pixel data where each bit represents one pixel (0 for white, 1 for black) packed eight per byte. There is no compression, no metadata, and no color — the format is purely a minimal container for delivering small monochrome graphics to WAP-era mobile browsers. One advantage was extreme efficiency on constrained devices — WBMP images could be decoded with virtually zero CPU overhead and minimal memory, critical on early mobile hardware running at single-digit megahertz clock speeds. The tiny file sizes are another strength: a typical WBMP icon occupied just a few hundred bytes, practical for transfer over 9.6 kbps GSM data channels. While the WAP ecosystem has been entirely superseded by modern mobile web browsers capable of rendering full-color JPEG, PNG, and WebP images, WBMP files remain encountered in archived mobile content from that transitional era.
