I'm an amateur photographer. I have Video, Mobile, Camera, Drone, etc. My goal is to sync all data on the right time and add GPS tag.
I end on configure everything on UTC (except mobile), and add after GPS tag that is on UTC also.
Main problem is how to determine correct timezone based on where the picture has been taken, and if I have to, since all my mobile photos has the timezone (and daylight savings) applied when taking video/photo.
I'm using now an OPEN API for having the correct GMT based on the geolocation and time/date.
Am I doing it right? Am I interpretating DATE/TIME changes correctly? I saw after that Lightroom changes based on the date/time info and the place it's used (photos).
It's a mess.
