| Purpose | Aduku Stacker combines focus-bracketed photographs into one sharp image for macro, product, landscape, and microscopy photography. | FocusFusion combines images with shallow depth of field into one image with greater depth of field. |
| Retouching | Users can paint from aligned source frames, erase strokes, and undo or redo retouching; the app does not yet have a clone tool. | A clone-based retouching tool lets users adjust brush size, hardness, and opacity; cloning is performed at 16-bit quality. |
| System requirements | The stated requirements are macOS 13 or later or 64-bit Windows 10/11; 8 GB RAM is sufficient for most stacks and 16 GB is recommended for deep 16-bit RAW stacks. | The app requires a Windows 10 PC with an SSE4.1 CPU manufactured after 2008 and at least 8 GB of memory; 16 GB is recommended for deeper stacks or larger DSLR images. |

In their own words
Aduku Stacker
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.
FocusFusion
FocusFusion is a free Windows application that combines photographs taken at different focus distances into one image with greater depth of field. It provides depthmap and wavelet focus-stacking algorithms, automatic alignment, and manual retouching. Depthmap expects images ordered front-to-back or back-to-front and can struggle with translucency or complex overlaps. Wavelet accepts images in any order, but may increase noise, create artifacts at sharp luminance transitions, or reduce alignment quality. Processing uses at least 16-bit precision per channel. Supported inputs are TIFF up to 48 bpp, 16-bit-per-channel JPEG XR, and classic 8-bit JPEG; RAW files are not supported. A clone-based retouching tool offers adjustable brush size, hardness, and opacity, with cloning at 16-bit quality. FocusFusion requires Windows 10, an SSE4.1 CPU made after 2008, and at least 8 GB of memory; 16 GB is recommended for deeper stacks or larger DSLR images. It is distributed through the Windows Store.
