Tornado Photography/Videography Tips:

My number one rule:
Live by it!
Other rules:
- Infinity focus.
- Use a TRIPOD! For video, use a fluid motion head.
- For stills, mix up focal lengths and formats (vertical and horizontal).
- For stills, largest aperature for shortest exposure time (or motion will blur).
- Be sure your date/time on your camera, and your GPS device, are syncronized with the Atomic Clock! This is useful for GPS tagging of the photo locations and helpful for NWS storm verification (accurate time and location).
