Okay, I will admit it. I’ve always snorkeled quietly in smug satisfaction when somebody sends me a video recorded vertically. When I’ve gotten over being smug, I calmly remind them that movies are shot in a horizontal format, not vertical. I then remind them that, if they take just two seconds to remember to turn their phone/camera on it’s side, they’ll get a much better looking movie.
By contrast, the vertical version of the same shot is just not as dramatic.
But this article makes a great, in fact, compelling case that proves to me I’m Wrong.
