Raw Photo Processor

The application is a raw‑image converter for macOS (10.4‑10.11) that focuses on early‑stage processing steps typically performed in film development. It offers a four‑channel white‑balance workflow with automatic, “as‑shot”, and custom neutral‑area options, as well as linear and compressed exposure compensation to preserve shadows and highlights. Integrated camera profiling uses the open‑source ArgyllCMS, and advanced saturation handling follows contemporary color‑science approaches.

Additional tools include brightness and contrast adjustments derived from film density measurements, three interpolation methods (VCDMF, AHDMF, and a half‑resolution recombination), highlights recovery for clipped channels, and a local‑contrast module based on the HiRaLoAm technique. A monochrome mode provides scientifically based black‑and‑white, sepia, and related outputs.

The software is intended for photographers who need precise raw conversion before further editing in programs such as Photoshop or Lightroom, and it supplies plugins for Lightroom versions 2‑5 to facilitate integration with those workflows.
