About formats

SRF (Sony RAW Format) is the earliest proprietary RAW image format used by Sony digital cameras, introduced in 2003 with the Cyber-shot DSC-F828 and also used by the DSC-V3 compact camera. SRF files capture the unprocessed sensor readout at 12 bits per channel, preserving the raw Bayer-pattern data from the camera's CCD sensor before any demosaicing, white balance, or compression processing. The DSC-F828 was notable for its unique 4-color RGBE (Red, Green, Blue, Emerald) CCD sensor design — an attempt to capture a wider color gamut by adding a cyan-shifted fourth color filter element — and SRF files from this camera store the raw 4-color mosaic data needed to take advantage of this unconventional sensor layout. The format uses a proprietary container structure with Sony-specific metadata tags recording exposure parameters, lens position, and camera settings. SRF was succeeded by SR2 and then ARW as Sony expanded into interchangeable-lens cameras with the Alpha DSLR system from 2006 onward. One advantage is the capture of data from genuinely innovative sensor technology — the DSC-F828's 4-color filter array was a unique experiment in consumer camera design, and SRF files preserve the raw 4-channel data that enables exploration of the extended color gamut this sensor design was intended to provide, particularly in the cyan-green portion of the spectrum where standard Bayer sensors have gaps. Despite the format's obscurity, SRF files remain processable: Adobe Camera Raw, dcraw, LibRaw, and RawTherapee all support SRF, ensuring these early Sony RAW files remain accessible for modern processing.

KWD is the native document format of KWord, the word processor component of KOffice (later renamed Calligra Suite), developed by the KDE community with its first stable release in KOffice 1.0 in 2000. KWord distinguished itself from other word processors through a frame-based layout model where text, images, and other content existed in independent frames that could be positioned freely on the page, similar to desktop publishing applications — a departure from the linear text-flow approach used by most word processors. KWD files store document content in a compressed XML format that describes the frame hierarchy, text content with formatting markup, paragraph styles, page dimensions, headers, footers, and embedded media. The format uses a ZIP container packaging the XML document alongside any referenced images and resources. One advantage was the flexible frame-based layout — users could position text and image frames independently on the page, enabling newsletter-style layouts and creative document designs without switching to a dedicated DTP application. The open XML structure is another benefit, making KWD files transparent and accessible to automated processing. KWord was included in several Linux distributions as part of the KDE desktop environment during the 2000s. The project was eventually discontinued in favor of Calligra Words, which adopted the ODF standard. KWD files can be opened with legacy KOffice installations or converted through document conversion tools.
