CalibRaw 1.0.0 RAW Photo Editor (r/opensource)

Hi, CalibRaw just got its first release :D. CalibRaw is a fully GPU-accelerated RAW editor focused on providing a smooth editing experience. LLMs were used in creating this program. Over the last 3 months, I tried to create a RAW editor that focuses on performance and a good workflow. I tried…

README

CalibRaw

CalibRaw is a fast, GPU-accelerated RAW photo editor.
It was made not to focus on design, but to be performant and non-destructive to the export.

I developed this project to provide a performant, approachable, open-source RAW editing workflow.
CalibRaw is available for Linux, Android, Windows, and macOS, with Linux and Android being the primary focus.

Download the latest release here.

Key Features

  • GPU-accelerated: Built with Rust, wgpu, and custom WGSL compute shaders for real-time performance.
  • Non-destructive: All edits and adjustments are non-destructive and saved to lightweight .calibraw sidecar files.
  • Advanced demosaicing: Features Bayer RCD, Fujifilm X-Trans (Markesteijn), and noise-resilient Dual Demosaicing.
  • Masking: Supports brush and shape masks with independent tone curves and adjustments.
  • Creative effects: Unique mask effects like light rays, lens blur, motion blur, fog, Glow, and more.
  • Optional AI: Local Subject & Object masks, AI Denoise, and AI object removal.
  • Multi-platform: Native builds for Linux, Android, Windows, and macOS.
  • HDR merge: Select 2 or more images to HDR merge them.
  • Automatic Lens Correction via Lensfun database
