In all program versions is a simple, autmatic calibration available.
For this kind of calibration is a special template required.
This template -see the image below- is designet for fields of view from 0,5 to 50 mm.
Templates for other fields of view on request.
The program recognizes how much from the template is visible. It is not nessessary to
promt any value.
So it is a fast and easy calibration, espacially for non-detend zoom lenses, too.
