I like many of us am a fan of Rachel Tailbart’s water and seascape images. Earlier today she posted some beautiful images of sand: https://www.instagram.com/p/DJZtiaXsIYo/?utm_source=ig_web_copy_link

Naturally the question came up of: How does she do that? Do you need a tripod with a boom so that your camera is on the same plane as your subject? Thanks for your help and I look forward to learning more.

Not sure, but it might be a drone shot.
