Kodak DC Series RAW
A raw format from the early consumer digital era.
KDC is a raw image format used by Kodak's consumer digital cameras (DC series) in the late 90s and early 2000s, such as the DC40, DC50, and DC120. Unlike the professional DCR format, KDC was aimed at the mass market.
KDC files are TIFF-based but use a specific compression and encryption scheme that made them difficult to open in third-party software for years. They contain raw sensor data, allowing for post-processing flexibility unavailable in standard JPEGs of that era.
Kodak was trying to bring better quality to consumer cameras. The format disappeared as Kodak shifted focus and eventually left the camera market.
Multiple-image Network Graphics
The ambitious, complex, and largely obsolete animated cousin of PNG.
MNG (Multiple-image Network Graphics) was designed as the animated equivalent of the PNG format. Just as PNG was created to replace GIF for static images, MNG was intended to replace GIF for animations, offering superior compression, full alpha transparency, and complex features like nested loops and sprites. However, its complexity led to poor adoption.
MNG is a stream-based format that shares the same chunk structure as PNG. It can contain embedded PNG (lossless) or JNG (JPEG-based) images. Unlike a simple filmstrip, MNG is a scriptable animation format; it supports 'sprites', frame deltas (only updating changed pixels), and complex composition rules.
Published in 2001 by the creators of PNG. Despite high hopes, browser vendors (like Mozilla) eventually removed support due to the large code footprint and complexity of the library (libmng). The simpler APNG format won the browser war for 'animated images'.
