Aduku Stacker vs Open Galileo

Aduku Stacker combines photographs taken at different focus distances into a sharp image, for macro, product, landscape and microscopy photography. The free app offers five merge methods: Wavelet, Pyramid, Weighted, Hybrid and Depthmap. Its default workflow processes images at 16-bit and uses 32-bit floating-point merge calculations, with memory-bounded batching for deep stacks. Automatic alignment uses feature matching and subpixel refinement; options include focus-breathing correction, homography, mesh warp and manual alignment seeding. It imports JPEG, PNG, TIFF, BMP, HEIC and DNG, and exports 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. Processing is local and does not require an internet connection. It runs on 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.

Open Galileo is free, open-source Windows software for focus stacking and signal integration in scientific photography, microscopy, macro photography, astrophotography, and technical documentation. It automatically aligns image sets with correlation algorithms, compensating for focus breathing and small shot differences. Focus fusion options include PMax multiband, weighted average, and depth-map methods. Astronomy mode combines signals using mean, median, sum, or sigma-clipping integration. Processing uses Laplacian, Difference of Gaussians, and variance focus measures, plus multiscale fusion with Laplacian pyramids. Optional tools provide contrast normalization, CLAHE, Unsharp Mask sharpening, and noise reduction including BM3D and approximate Noise2Void. Folders can be processed and saved automatically. JPG, PNG, TIFF, and RAW files are supported. The interface includes live previews, progress bars, parameter sliders, and a large-screen layout.
