To me, lighting is one of the most difficult things to do effectively. People dedicate their entire lives to the art of lighting. For the sake of this article I’ll just say this: You need to see what’s being shown. You’re saying “well duh!”, but I can’t tell you how many local commercials I’ve seen that are not lit effectively. All it would have taken is a couple of lights to change the whole shot. On the other end of the spectrum, is the scene blown-out and are the shadows horrible or is the lighting diffused and pleasing to the eye?
Okay, let's touch on audio. This is pretty straight forward. Can you hear the talent or announcer? Is the music at a correct level with the voiceover? Is all the audio mixed together well? Was the on-camera mic used to capture the speaking parts or a professional microphone? It is simple but can influence so much. I can stand watching a commercial with less-than-great video, but if the audio is awful, I change the channel immediately.
