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.
Kodak Cineon
A pioneering 10-bit logarithmic format designed by Kodak for digital film scanning and mastering.
The Cineon format (.cin) was developed by Kodak in the early 1990s as part of their Cineon Digital Film System. It was designed to capture the full dynamic range of film negatives. Unlike standard linear image formats, Cineon stores data in a 10-bit logarithmic density format, which closely mimics the response of film to light. This allows it to preserve highlight and shadow details that would be lost in linear 8-bit formats.
Cineon files use 10 bits per color channel (Red, Green, Blue), packed into 32-bit words (with 2 bits of padding). The key feature is the logarithmic encoding: pixel values represent printing density rather than linear brightness. A value of roughly 95 represents 'D-min' (clear film base), and the values scale up to represent increasing density. This allows the format to store a dynamic range that exceeds standard video formats.
Introduced in 1993, the Cineon system was the first end-to-end 4K digital intermediate workflow for motion pictures. While the hardware system was discontinued in 1997, the file format became the industry standard for visual effects and digital mastering until it was eventually superseded by the more flexible DPX (Digital Picture Exchange) format, which is directly based on Cineon.
