About:
Negfix8 is a specialized command-line utility that processes scanned negative film images and automatically converts them into positive prints. It analyzes image data to correct color inversion, adjust exposure, and balance color channels to approximate a true photographic positive from a negative source.

Key Features:

Automatic color correction and inversion for film negatives
Command-line interface for batch processing workflows
Outputs standard image formats compatible with other tools
Lightweight and focused on a single task

Use Cases:

Digitizing old film negatives without access to a dedicated film scanner
Automating conversion of large archives of negative scans
Creating positive prints from negatives as a step in a manual editing workflow

Alternatives:

negfix8 (original) – The original tool this formula packages; Homebrew provides easier installation on modern macOS
ImageMagick – More general-purpose tool that can invert colors but lacks specialized film negative algorithms
Darktable – Full-featured RAW editor with film negative modules, but much heavier and GUI-based
