FocusFusion vs Helicon Focus

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.

Helicon Focus combines photographs captured at different focus distances into one image with extended depth of field. It is designed for focus stacking in macro and micro photography, close-ups, jewelry, products, landscapes, flowers, animals, and still life. The software processes images at 16-bit precision, supports color profiles, opens RAW files, and can save Pro results as DNG. It handles stacks of hundreds of high-resolution images and supports unlimited stack length. Retouching tools copy areas from aligned source images or combine areas from outputs, with a grid for detailed work. Batch rendering can queue and split stacks, while command-line parameters allow calls from other applications. Lightroom and Capture One plugins export stacks. Pro features add 3D model export and 2D micropanorama stitching. Current downloads support 64-bit Windows 10 or 11 and macOS 12 or later. A fully featured trial lasts 30 days; Demo mode then limits resolution and adds a watermark.
