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.

PDB (Palm Database) is a generic database container format created by Palm, Inc. for the Palm OS platform, first appearing with the original PalmPilot in March 1996. In the ebook context, PDB files most commonly use the PalmDOC or Plucker encoding to store readable text with basic formatting. The format consists of a 78-byte header identifying the database name, creation date, and record count, followed by a record index table and the data records themselves. PalmDOC-encoded PDB files use a simple LZ77-based compression scheme to pack plain text efficiently, while Plucker extends this with HTML rendering, image support, and hyperlink navigation. PDB ebooks powered a thriving mobile reading ecosystem years before dedicated e-readers existed — millions of Palm OS users carried entire libraries on devices like the Palm V, Tungsten, and Treo handhelds. A primary advantage is extreme simplicity: the flat record structure and minimal overhead mean PDB files parse instantly even on severely constrained hardware with limited memory and processing power. The open, well-documented structure is another strength, having spawned numerous reader applications across Palm OS, Windows, and later mobile platforms. Though the Palm platform is long discontinued, PDB ebooks remain accessible through conversion tools and readers like Calibre, and the format holds historical significance as one of the earliest practical mobile ebook solutions.
