ShineStacker is a focus stacking tool with an interactive GUI and a Python API, designed for advanced image processing workflows in macro photography and microscopy.

• 🪟 Cross-Platform GUI: Native app built with Qt6, available for Windows, macOS, and Linux.
• 🚀 Batch Processing: Automatically align, balance, and stack hundreds of images — perfect for macro or microscopy datasets.
• 🧩 Modular Architecture: Combine configurable modules for alignment, normalization, and blending to build custom workflows.
• 🖌️ Retouch Editor: Interactively refine your stacked image by painting in details from individual frames.
