No vertical video! That was the first of many useful tips for journalists on recording video with a mobile device, offered up during a program devoted to multimedia. Here are others: -Put the light source behind you, NOT behind your subject. -The subject should comprise about a third of the frame, on the left or right- NOT in the middle. -Put your device about an arm's length from the subject to capture the best possible audio. -Stand to the side, so that when your subject looks at you, he or she appears to be looking into the empty part of the frame. -Set your phone to airplane mode to preclude interruptions. -Ask the subject to spell his or her name on camera, with title. -Clear as much phone memory as possible in advance. Keep interviews short.
