Yup. Anything commercial requires (currently) a 333a exemption. As said above.
That’s why everything I do is for fun and a hobby. I never get paid for anything related to aerial photography. The rules are about to change and it will be interesting to see what comes of it.
I used to be into FPV racing, but that wasn’t as fun as it first seemed to me. Plus flying FPV is pretty much illegal in the current onslaught of FAA/AMA rules. That’s why they usually choose indoor places such as stadiums or warehouses.
