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.
Portable Bitmap
The lowest common denominator of image formats.
PBM (Portable Bitmap) is the simplest format in the Netpbm suite, designed to represent monochrome (black and white) images. It uses a straightforward text-based (or simple binary) encoding where '1' represents black and '0' represents white (or vice versa depending on the viewer, though standard entails 1=black). It was designed to be easily emailed and processed by simple scripts.
There are two variants: P1 (ASCII) and P4 (Binary). ASCII P1: The file is human-readable text. A grid of 0s and 1s defines the image. Binary P4: The bits are packed into bytes for efficiency. The header simply states the magic number (P1 or P4) and the dimensions. There is no compression, no index, no palette.
Invented by Jef Poskanzer in the 1980s as a way to send bitmaps via email properly. It became the foundation of the 'pbmplus' (later 'netpbm') toolkit, which provided a standard way to convert between dozens of incompatible 80s file formats.
