focus-stack vs Macro Studio

focus-stack is a free desktop program that combines photographs taken at different focus settings into an image with extended depth of field. For each pixel, it selects the sharpest source image, a method documented for uses such as microscope photography. The tool can resize and rotate stack images to align them, or alignment can be skipped or adjusted. Outputs include a focus-stacked image, an optional depth map, and a 3D preview based on that map. Input formats supported by OpenCV include JPG, PNG, and TIFF, while the filename extension determines output format. Processing controls cover denoising, consistency filtering, batch size, and thread count. OpenCV’s OpenCL interface provides GPU acceleration when available, with an option to disable it. Binary packages are listed for Windows 10, Ubuntu 20.04, and Mac OS X. The project is MIT licensed; Linux builds require OpenCV 3.0 or newer and basic build tools.

Macro Studio is desktop software for focus stacking and non-destructive editing in macro photography. It analyzes focus-bracket images and merges their sharp areas into one image, with automatic alignment and batch processing listed. The editor includes adjustments, masks, retouching, cropping, image comparison, and watermarks; it also supports RAW files and TIFF, JPEG, and DNG output. AI-assisted tools provide subject masks, species identification, and draft social posts. Macro Studio runs on Linux, macOS, and Windows. Listed integrations include Adobe Bridge, Lightroom Classic, DxO PhotoLab, and ON1 Photo RAW. Its Lightroom plugin works with Lightroom Classic, not the cloud-based Lightroom app. The maker says photos stay on the user's machine and are not used to train AI. The Macro Studio 2026 license is $59.00 USD as a one-time purchase, with a launch price shown as reduced from $99. It includes all features, use on up to three machines, and updates within the 2026 version. Free trials are invite-only, last 30 days, and unlock every feature.
