FocusStacker for iOS is billed as the first-ever calculating tool for photographers using the focus stacking technique. You can specify how sharp you would like your final image to be, set focal length and the distances to the nearest and furthest objects in the scene you’re photographing, and then let FocusStacker determine exactly what you need to know: the minimum number of shots to take, the distances on which to focus, and the aperture to use. Do note, however, that FocusStacker is not suitable for close-up or macro photography.

Introducing FocusStacker: Focus stacking in landscape and architectural photography—without the guesswork
Melbourne, Australia — May 31, 2013 — FocusStacker, the first ever calculating tool for photographers using the focus stacking technique, is available now on iPhone and iPod Touch.
The focus stacking technique seems simple: take multiple shots of the same scene—each shot focused at a different distance—and then combine those shots in focus stacking software to create a sharper image over much greater depth than would be possible with a single shot.
But how many shots should you take? On what distances should you focus? And what is the ideal aperture to use? Look for informed answers to these questions, and you won’t find any — until now. FocusStacker makes guesswork a thing of the past. Specify how sharp you would like your final image to be, set focal length and the distances to the nearest and furthest objects in the scene you’re photographing, and then let FocusStacker determine exactly what you need to know: the minimum number of shots to take, the distances on which to focus, and the aperture to use.
Significantly, by using FocusStacker you’ll know exactly what results to expect as you work out in the field—so much better than getting back to the studio, running your shots through focus stacking software and finding, too late, that things aren’t quite right.
FocusStacker is designed for use in landscape and architectural photography. In its speed, elegance and accuracy, it fits the needs of professional photographers, who’ll be happy to know that at its heart lies the sophisticated optimisation algorithm originally developed for the OptimumCS-Pro app. And yet, FocusStacker is so easy to use that anyone can have a go at focus stacking.
1. FocusStacker is not designed for and is NOT suitable for close-up or macro photography.
2. You’ll need a camera that enables you to adjust focus and aperture manually, and a way to measure distance (e.g. a distance scale on a lens, or a camera that reads out focus distance, or a laser rangefinder, etc). And you’ll need a tripod.
3. Focus stacking is best suited to static subjects.
FocusStacker is available now on the App Store.
