phaios 0.1.1

Dedicated black-and-white RAW developer

phaios

φαιός — dusky grey (Aristotle, De Sensu). A dedicated black-and-white RAW developer for the desktop.

phaios converts colour RAW files (NEF, CR2/3, ARW, RAF, DNG) to monochrome using the canonical B&W photographic techniques: standard luminance weights, channel mixing, and coloured-filter simulation. The numerical pipeline is powered by the phaios-core Rust extension.

Quick start

pip install phaios
python -m phaios              # launch the desktop app

Requires Python 3.12+ and a supported platform (Linux x86-64, Windows x86-64, macOS arm64).
