Phones ringing, dogs barking, kids playing, fans blowing, squeaky chairs, nervous tapping or banging . . . They will in no way enhance the broadcast ability of your video, but only detract from it. Amateur videographers are not aware that professionals will tell you to use roughly five times more light on your subject that what the human eye thinks is necessary. The professionals are right. You can never have too much light, but you sure can have too little.
Sufficient light is easy to get.
We started out taping testimonies by simply going to the hardware and purchasing a couple of aluminum reflector, clamp-on style lights, and putting 300 watt bulbs in them. Obviously it takes awhile for people to get used to bright lights in their eyes, but they adjust to it after a few minutes of speaking. Direct light on the testifier' s face is fine. You might shine it down at an angle on them to eliminate glare on their eyes. Try to stay away from harsh shadows from the nose and under the eyes.
