What it is
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.
