What's New in FocusStacker

4.1

September 23, 2018

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!

Excellent, Smart Calculator

This is an excellent interactive visual calculator for optimizing focus distances and aperture when focus stacking. It may be more optimized than necessary in many field situations, but if you need the best guidance and have the time to apply it, you will be pleased.

Nothing but a chart.

This is just and interacive chart. It does NOTHING! I paid $9.99 for a chart. Save your money.

Be Careful: READ THE DETAIL

Hidden in the deep text. This app is a visual spreadsheet, not a cool app that actually uses you mobile to create great pictures. Do some research, make your own spreadsheet and forget about this app. It will take you a week or more before you'll actually know if this app is any good. Select setting, make notes, setup camera manually, take shots, export data, buy stacking software, import data, fiddle about learning new software..... get a result... hmm was it worth it?

Without this tool, you are merely guessing on the decisions you need to make.

How many shots? Where are the shots focused? What f/stop?

Yes, photography is an art, but this part of it is a science. So if you want to get the very best results from your camera and lens, do yourself a favor and get this app.
