If you are filming for any reason, team or professional, you must register with the SCTA's Holly Martin. She will give you the guidelines of what you can and can't do and where you can and can't go. and what you need to have in your vehicles - CB radios and such
Team videographers are not charged to film/shoot (sorry old school), but commercial, not matter large or small, are charged a day rate to shoot.
And don't break out the drones without special permission (official flight training) and fight rules, no flying over the crowds or running down the course.
But is it worth it??? You BET!!!
I started out as a photographer of sorts, some like my work, and now I own a race team with my wife and major help from my friends and we even have sponsors!
