"films" world also work. or "narwhal's shown to use tusks... in the wild via drone footage". or any number of other ways.
Explaining film to a kid that only knows digital cameras was not so easy. "You edit it by cutting long strips apart and taping it back together." "You have to go into a dark room and wash the film in chemical baths." Sounds like some sort of magic ritual.
Now I am wondering if I just think the look of film is better because that is what I watched when I was a kid. Maybe todays kids will think digital looks better.
