Lumi-o

Lumi is a fast, efficient, Linux-only application for raster image making, developed in the open. Its design decisions, architecture documents, and development history are public so users can understand how it evolves.

Lumi is biased toward digital painting and illustration while remaining capable of structured image editing and photographic correction. Corrective adjustments, lens style effects, tone based color grading, and non destructive filter layers support a wide range of editing workflows.

Lumi is built around the idea that digital painting software should behave like a dependable studio tool: predictable, transparent, and focused on the act of making images.
