FocusStacker 4.1

Focus stacking is an advanced photographic technique that involves capturing multiple images of the same scene, each focused at different distances. By combining these images using specialized focus stacking software, photographers can produce a sharp final image that exhibits greater depth of field than what is typically achievable with a single shot.

The software designed for photo stacking is generally user-friendly; however, the process of capturing the initial shots raises important questions: How many images should be taken? At which distances should the focus be adjusted? What aperture settings will yield the best results? FocusStacker addresses these concerns, eliminating speculation and providing precise guidance tailored to the desired sharpness standard. It specifies the minimum number of shots required, the corresponding focus distances, and optimal aperture settings.

Primarily intended for landscape and architectural photography, FocusStacker is built to meet the demands of professional photographers. It boasts speed, efficiency, and accuracy, featuring a sophisticated optimization algorithm originally developed for the OptimumCS-Pro application, which has been adapted for use in capturing multiple frames. Despite its advanced capabilities, FocusStacker remains accessible enough for enthusiasts to engage in focus stacking.

• FocusStacker is not designed for, nor suitable for, close-up or macro photography.
• For quality focus stacking software alternatives, consider Zerene Stacker at http://zerenesystems.com/stacker/.
• A camera that allows manual adjustments of focus and aperture is required, along with a means to measure distance (e.g., distance scale on a lens or laser rangefinder). A tripod is also essential.
• FocusStacker functions exclusively as a calculating tool and does not interact with the built-in cameras of iPhones or iPads.
• It is important to note that focus stacking is most effective with static subjects.
