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.
Developer: Sony
Initial release: 2003
EPUB (Electronic Publication) is an open ebook standard originally developed by the International Digital Publishing Forum (IDPF) and now maintained by the W3C following the organizations' merger in 2017. The first version carrying the EPUB name was approved in October 2007 as a successor to the Open eBook Publication Structure (OEBPS). An EPUB file is essentially a ZIP archive containing XHTML or HTML5 content documents, CSS stylesheets, images, fonts, and metadata organized according to the Open Packaging Format and Open Container Format specifications. The current major version, EPUB 3, supports reflowable and fixed-layout content, embedded multimedia, JavaScript interactivity, MathML equations, and rich accessibility features including semantic markup and media overlays for synchronized text and audio. A defining advantage is universal device support — unlike proprietary formats, EPUB works natively on virtually every non-Kindle e-reader, tablet, and reading application, from Apple Books and Google Play Books to Kobo and dozens of third-party apps. The reflowable text model is another core strength, automatically adapting pagination, font size, and margins to match any screen dimension and user preference. EPUB's open specification and active W3C stewardship ensure long-term preservation and vendor independence, making it the de facto standard for digital publishing across libraries, academic institutions, and commercial retailers worldwide.
