Shooting in HD requires professional equipment? If you're just doing it as a hobby, there's no need to make a big fuss or spend a lot of money. An iPhone plus an iPhone-specific tripod will do!
Don't think this is something the editor came up with on a whim; these iPhone-specific tripods are already available for sale. On a website called isteadyshot.com, they specialize in selling this gadget. It's very well-made and not too expensive. At $99.95, it converts to just over 600 RMB. Unfortunately, it's not yet available domestically, so for now, we can only admire it from afar.
