Thanks for the replies, everyone! Iceland restricts drone usage at the most popular tourist sites. I, basically, drove along the highways until I found something I wanted to film and stopped at a pull-off area, set up my drone, and flew. The black beach scenes were at a very popular area, but I tried to keep people out of the footage. I almost lost my drone there as the winds were 40-50mph, but I had to get the footage. It was breathtaking. There were no signs in those areas restricting usage. Still, this was only the southern/southwest part of Iceland, which is the most frequently visited, so next time I hope to film western and northern Iceland, as they are much more remote and have less tourists. Timing of the year is key too as summer is the busiest. Winter is great scenery but roads may be closed due to winter storms. All in all, it was an incredible experience. If you get the chance to go, do it. It's a videographer/photographer's dream.
