KDC to PPM Converter

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.
