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.

DjVu (pronounced "deja vu") is a document format developed at AT&T Labs by Yann LeCun, Leon Bottou, Patrick Haffner, and Paul Howard, first released in 1996. The format was specifically designed for storing scanned documents and images at very high compression ratios while maintaining visual quality suitable for on-screen reading. DjVu achieves this through a layered approach: the document image is separated into a foreground layer (text and line art at full resolution), a background layer (photographs and textures at reduced resolution), and a mask layer that determines which layer is visible at each pixel. This separation, combined with purpose-built compression algorithms for each layer type, typically produces files 5-10 times smaller than equivalent JPEG or PDF scans. One advantage is exceptional compression on scanned pages — a 300 DPI color scan that might occupy 25 MB as TIFF or 500 KB as JPEG typically compresses to 40-80 KB in DjVu while preserving legible text. The progressive rendering model is another strength: DjVu files stream efficiently over networks, displaying a readable low-resolution version almost immediately while progressively refining to full quality. The format supports multi-page documents, embedded text layers for searchability, hyperlinks, annotations, and a shared dictionary mechanism that further compresses collections of similar pages. DjVu is widely used by libraries and archives for digitized historical documents and manuscripts.
