About formats

KDC is a proprietary RAW image format used by Kodak's DC (Digital Camera) and EasyShare consumer camera lines, first appearing in 1995 with early models like the DC40. KDC files capture the unprocessed sensor data from Kodak's CCD image sensors before any in-camera demosaicing, white balance, sharpening, or compression is applied. The format spans a wide range of sensor resolutions across Kodak's consumer camera history, from sub-megapixel early models through the multi-megapixel EasyShare cameras of the mid-2000s. KDC stores the raw Bayer-pattern data alongside camera-specific metadata including the sensor's color filter array layout, exposure parameters, and Kodak's proprietary color matrix coefficients that define how raw sensor values map to visible colors. While Kodak eventually exited the consumer camera market, KDC files from these cameras represent an important historical record of early consumer digital photography. One advantage is access to Kodak's renowned color science — even in their consumer cameras, Kodak's sensor designs and color processing produced distinctive, film-like color rendering, and KDC files preserve the raw data needed to explore this color character with modern RAW processing tools that can apply the original Kodak color matrices or alternative interpretations. Practical longevity is another strength: KDC format support is maintained in Adobe Lightroom, dcraw, LibRaw, and RawTherapee, ensuring that images captured on Kodak consumer cameras remain processable with contemporary software long after the hardware was discontinued.

TCR (Text Compression for Reader) is a compressed plain-text ebook format developed by Barry Childress in the early 1990s for the Psion Series 3 family of palmtop computers. The format was created for Childress's Reader3 application, a text file viewer that needed to fit large books into the Psion's extremely limited storage — typically 128 KB to 2 MB of available memory. TCR uses a dictionary-based compression scheme derived from the earlier ZVR format by Ian Giddings, replacing repeated byte sequences with single-byte tokens that reference a header dictionary. This straightforward approach achieves compression ratios of roughly 40-60% on typical English prose while requiring minimal CPU resources for decompression. The Psion Series 3 ran on a 3.84 MHz NEC V30 processor with no floating-point unit, so TCR's low computational overhead was essential for smooth page-by-page reading. A key advantage is remarkable storage efficiency for its simplicity — users could carry dozens of novels on removable SSD cards that held only a few hundred kilobytes. The format found a dedicated user community among Psion enthusiasts who built libraries of compressed literature for portable reading years before smartphones existed. Though the Psion platform faded from the market in the early 2000s, TCR files can still be opened and converted by modern ebook tools, and the format stands as an early example of purpose-built mobile reading technology from the pre-smartphone era.
