About FocusStacker
Focus stacking is a technique in which you take multiple shots of the same scene—each shot focused at a different distance—and then combine them in focus stacking software to create a sharp image over much greater depth than would be possible with a single shot.
The software for stacking photos is simple and easy to use. But what about the process of taking the shots? How many shots should you take? On what distances should you focus? And what is the best aperture to use? This is where FocusStacker comes in, making guesswork a thing of the past. For the particular image sharpness standard that you specify, FocusStacker determines exactly what you need to know: the minimum number of shots to take, the distances to focus on, and the aperture to use.
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 optimization algorithm originally developed for the OptimumCS-Pro app, adapted here to the taking of multiple shots. Yet it’s so easy to use that anyone can have a go at focus stacking.
Note:
1) FocusStacker is NOT designed for and is NOT suitable for close-up or macro photography.
2) For quality focus stacking software, try Zerene Stacker, http://zerenesystems.com/stacker/
3) You’ll need a camera that enables you to manually adjust focus and aperture, 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.
4) FocusStacker is a calculating tool—it does not access or use the iPhone's or iPad's built-in camera.
5) Please be aware that focus stacking is best suited to static subjects.
6) Additional information is available at www.georgedouvos.com

What's New in the Latest Version 4.1
Last updated on Sep 23, 2018
Old Versions
This is a wee update to bring support for iOS 12 and the various new iPhone X models.
Don't forget all the Version 4.0 updates:
* The interface gets a cleaner look. Simply slide the pointers on the distance scale or the blur diameter scale to set inputs (the old slider “thumbs” are now gone). Note that you do not need to keep your finger on a pointer as you slide it — you can move your finger to the side as you slide, all the better to see where the pointer is pointing.
The pointers themselves also display digital readouts.
A warning is now displayed if your inputs are such that an excessively large number of shots would need to be taken (“excessively large” is defined in this app as >10).
Enjoy!

Note that you do not need to keep your finger on a pointer as you slide it — you can move your finger to the side, all the better to see where the pointer is pointing.
The pointers themselves also display numerical readouts of distance. The slider for selecting blur size gets a similar treatment, including a numerical readout of image blur.
A warning is now displayed if your inputs are such that an excessively large number of shots would need to be taken (“excessively large” is defined in this app as >10).
There are all manner of minor changes, including a more punchy colour scheme.

A more pleasant colour scheme, plus several small interface tweaks.
Of course, all the new features of the last major upgrade are still there:
• The slider for setting how sharp you want your image to be is now on the main screen.
• Assistance is provided in setting reasonable upper and lower limits for image blur.
• A visual indicator of these limits is shown on the main screen.
• Distance units are changed directly on the main screen by tapping the m / ft button.
• Three different distance scales are provided.
• Labels can be hidden, for a cleaner interface.
• Several info (help) buttons have been added.
And there are lots of other, smaller improvements.
Oh, and there's a new icon, and the file size is much smaller.
Enjoy!

If you’re using focus stacking for landscape photography, and using FocusStacker to get the best possible results, you’re at the cutting edge in photography. Or so you thought! Now, if you’re adventurous, you can take things even further: How about trying focus stacking in infrared photography? For infrared (or ultraviolet) work, the facility to specify wavelength, as recently introduced to the OptimumCS-Pro and TrueDoF-Pro apps, has been added to FocusStacker.

iOS 7 compatibility.
Also...
Changed the action of the focal length scroll wheel:
- The scroll wheel now responds much faster when you tap the focal length “Up” and “Down” buttons.
- Scrolling now results in real-time update of outputs (rather than having to wait till the wheel settles on your final choice of focal length).
- The wheel no longer free rotates after you stop pushing it.
