Aduku Stacker combines photographs taken at different focus distances into a sharp image, for macro, product, landscape, and microscopy photography. It runs on macOS 13 or later and 64-bit Windows 10/11, and is listed at 0.00 USD per free. Users can choose Wavelet, Pyramid, Weighted, Hybrid, or Depthmap merging. The default workflow processes images at 16-bit and uses 32-bit floating-point merge calculations; memory-bounded batching is available for deep stacks. Alignment includes feature matching and subpixel refinement, with options for focus-breathing correction, homography, mesh warp, and manual seeding. Supported imports include JPEG, PNG, TIFF, BMP, HEIC, and DNG; exports include JPEG, PNG, TIFF, linear DNG, and depth maps. Proprietary RAW files may require Adobe DNG Converter on macOS. Retouching lets users paint from aligned source frames, erase strokes, and undo or redo, but there is no clone tool. Image processing happens locally and does not require an internet connection. The focus-stacking engine is also available as a command-line tool for scripted batch processing.
