FocusFusion vs ForgePix

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.

ForgePix is beta software for automatic focus stacking and computational photography, with workflows for macro, astrophotography, and long-exposure image series. Its Macro, Astro, Hybrid, and Long Exposure modules include a one-click Automatic mode that selects usable frames, aligns and merges them, then applies gentle sharpening. Focus merges can use Laplacian pyramid, depth map, weighted average, à-trous wavelet, or halo fix methods. Astro tools cover calibration-frame detection, star alignment, rejection methods, drizzle, multi-session stacking, and FITS export. Editing and output features include RAW support, a Camera-Raw editor, retouch brush, batch processing, watch folder, and export presets for JPG, TIFF, layered Photoshop TIFF, and FITS. ForgePix says processing is fully local and does not require AI, a server, or external astronomy software. Optional language assistants and external tools are available. Assistant setup sends preview frames, sharpness profile, basic EXIF data, and the user's wish, but not original files or location data. Experimental local AI image models are not enabled by default and may alter faint structures, flux, or star shapes. ForgePix is free under the MIT license, with downloads for Linux, macOS, and Windows.
