I just watched a video on YouTube about the PolarPro app and want to recommend it to your attention. The YouTube URL is:
. It basically recommends ND filter classification and camera settings, but among its other features is a reading of the KP index which I knew very little about but will now monitor closely. The index (see Wikipedia K-index - Wikipedia ) measures geomagnetic storms and could be the reason for some fly-away incidents.
The app is free (ad supported) and gives you basic info such as time, wind speed and temperature in addition to the KP index. In addition it also provides info on still and video shooting settings and recommends the proper ND filter for the speed and aperture you want to use when shooting. Those recommendations are non-brand specific. I have downloaded it and am presently reviewing it. Given the hazard of fly-away incidents, the KP index reading along is worth the time and trouble of installing the free app. Let me know what you think.
