OpenFocus vs PlaneFuse

OpenFocus aligns and fuses multi-focus image sequences to create images with focus throughout. It offers ECC and Homography alignment and several fusion methods: Guided Filter, DCT, DTCWT, GFG-FGF and the StackMFF V4 AI model. A wipe view lets users compare source frames with results, and the software can generate depth maps showing focus position per pixel. It supports folder-based batch processing and a headless command-line interface for scripting and CI. Listed inputs include JPG, PNG, BMP, TIFF, MP4 and numbered image folders; the manual also describes decoding additional video formats. Outputs include those image formats, image-sequence folders and GIF animations. Research functions include metadata-calibrated scale bars and multi-page TIFF stacks that preserve 16-bit depth. The interface supports English, Chinese, Japanese and Spanish, with automatic system-language detection. OpenFocus is free under the MIT License, though included algorithms may have separate license terms. Its Windows and macOS app builds are unsigned and may trigger SmartScreen or Gatekeeper warnings on first launch.

PlaneFuse is free focus-stacking software for macro, product, and landscape photography. It combines frames captured at different focus distances using PMax, DMap, weighted average, or Slab methods. Alignment options include translation, similarity, and perspective; it can reject poorly aligned frames and thin redundant brackets. For RAW stacks, it fuses frames from the same camera and sensor mode in scene-linear RGB and exports a re-editable Linear DNG. The process requires irreversible demosaicing. Its local browser workspace has deep zoom, source and result comparisons, a live histogram, and a reorderable job queue. Non-destructive retouching can work with source frames or results; exports include TIFF, PNG, JPEG, Linear DNG, and depth maps. NVIDIA CUDA and Apple MPS acceleration are supported, with CPU fallback and tiled processing if GPU memory runs out. PlaneFuse also offers command-line and local HTTP and WebSocket interfaces for scripting and batch work. Processing stays on the computer without uploading photos. The software is free for personal and commercial use; initial setup requires Node.js and uv.
