Zerene Stacker
Zerene Stacker is a specialised focus-stacking application used in macro and microscopic photography to combine multiple images taken at different focal planes into a single image with extended depth of field. It uses advanced alignment and blending algorithms to seamlessly merge image series, and includes tools for manual retouching and fine-tuning the final result. It is widely used by serious photographers, macro enthusiasts, and researchers who need critical sharpness throughout complex three-dimensional subjects. The software runs on Windows, macOS and Linux, and is available in both free trial and licensed Pro versions.

1 suggestionZerene Stacker already ships a native Universal Binary build that runs natively on Apple Silicon, so there is nothing to worry about. The developer's current production version (as of May 2026) is a Universal Binary that supports both Apple Silicon and Intel Macs and explicitly states "Rosetta is no longer required for this build." Simply download the latest version from zerenesystems.com/cms/stacker/softwaredownloads — look for the macOS universal build (ZS-macOS-universal-*.zip). It will run natively on M-series Macs with full performance and no Rosetta emulation required. If you are currently running an older Intel-only version of Zerene Stacker, updating to the universal build will give you noticeably better performance, faster stacking times, and improved battery life on Apple Silicon hardware.
