About formats

MRW is the proprietary RAW image format developed by Minolta (later Konica Minolta) for their digital SLR and advanced compact cameras, introduced in 2001 with the DiMAGE 7, one of the first consumer-grade digital cameras to offer RAW capture alongside JPEG. MRW files capture the unprocessed 12-bit readout from the camera's CCD sensor in its native Bayer mosaic pattern, storing the data in a container format with a series of tagged data blocks for the raw image, camera settings, and proprietary metadata. The format was used across Minolta's digital camera lineup including the DiMAGE A-series advanced compacts and the Dynax/Maxxum 5D and 7D digital SLRs — the latter being the first DSLRs with built-in sensor-shift image stabilization, a technology later inherited by Sony when they acquired Konica Minolta's camera division in 2006. MRW files preserve the original sensor values needed for high-quality demosaicing, custom white balance, and exposure adjustment, giving photographers flexibility unavailable with the camera's in-body JPEG processing. One advantage is historical technological significance: MRW files from the Dynax 7D and its predecessors document the pioneering implementation of in-body stabilization and other innovations that became industry standards, and the RAW data preserves these early captures in their most flexible form. Continued compatibility is another strength — MRW files are supported by Adobe Lightroom, dcraw, LibRaw, RawTherapee, and other modern RAW converters, keeping these Minolta-era digital negatives fully usable with current processing algorithms.

LRF is the file format associated with Sony's BBeB (Broadband eBook) specification, jointly developed by Sony and Canon and introduced in 2004 with the Sony Librie EBR-1000EP — the world's first commercial E Ink e-reader. The format supports both reflowable text and fixed-layout page rendering, embedding fonts, images, vector graphics, and metadata within a compact binary container. LRF files use a block-based internal structure with object trees describing page layouts, text streams, image resources, and table of contents navigation. Sony's Reader devices and the companion desktop software (Sony Reader Library) served as the primary ecosystem for LRF content throughout the mid-2000s. A key advantage was its early adoption of high-quality font embedding and text rendering optimized specifically for E Ink displays, delivering a reading experience noticeably superior to many competing formats of the era. The format also supported bookmark synchronization, dictionary lookups, and annotations within the Sony Reader ecosystem. However, Sony officially discontinued BBeB/LRF support in 2010, migrating its Reader platform to the industry-standard EPUB format. Today LRF files are primarily encountered in personal ebook collections from that period and can be converted to modern formats using tools like Calibre. The format remains a historically significant milestone as the native format of the device category that launched the modern e-reader revolution.
