3.1
2018-09-27
This is just a wee update to bring iOS 12 compatibility and support for the various new iPhone X models.
Don't forget all the Version 3.0 changes:
* The interface gets an even cleaner, more spacious look. Simply slide the pointers on the distance scale to set distances (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.
* There are also all manner of minor changes.
For a host of additional features (too numerous to list here) check out the "Pro" version, OptimumCS-Pro, here on the App Store.

2.1

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 display of image sharpness in line pairs per mm (a concept more familiar to physicists than photographers) has been replaced with a display showing blur spot diameter (circle of confusion).
• A marker can be placed on the blur spot diameter scale as a reminder of what you consider acceptable blur sizes.
• Distance units are changed directly on the main screen by tapping the m / ft button.
• A couple of info (help) buttons have been added.
And there are lots of other, smaller improvements.
Enjoy!

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 output (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.
