Aduku Stacker

Summary

Aduku Stacker combines photographs taken at different focus distances into a sharp image, for macro, product, landscape, and microscopy photography. It offers Wavelet, Pyramid, Weighted, Hybrid, and Depthmap merge methods. Its default workflow processes images at 16-bit and uses 32-bit floating-point merge calculations; memory-bounded batching is available for deep stacks. Alignment can use feature matching and subpixel refinement, with focus-breathing correction, homography, mesh warp, and manual seeding as options. It imports JPEG, PNG, TIFF, BMP, HEIC, and DNG, and exports JPEG, PNG, TIFF, linear DNG, and depth maps. Proprietary RAW files may need 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. Processing is local and needs no internet connection. It is free for macOS 13 or later and 64-bit Windows 10/11; 8 GB RAM is sufficient for most stacks, with 16 GB recommended for deep 16-bit RAW stacks.

Who it is for

It suits photographers combining focus-bracketed images, including macro, product, landscape, and microscopy work. The command-line engine may also suit people scripting batch processing.
