What The Couple Wants:
A beautiful wedding. This may involve a candlelit setting with romantic lighting that defines the venue. You may want the dance floor to be dark when everyone is dancing (most people prefer this since it lowers inhibitions). You also may not want your photographer and videographer to be very noticeable and distracting. Anyone who has had a light shined in their eyes or has seen the glaring light bobbing up and down in the dance crowd understands this. Lights on stands are rarely attractive in a ceremony or reception setting.
What Videographers Want:
Light, light, and more light. Ever been on a movie set? Using 1,000 to 100,000 watt lights is commonplace to give the cameras the light the movie cameras need. So wedding videographers tend to want the same, since without appropriate lighting the footage will not be viewable. Unfortunately there is no such thing as flash videography (photographers have it made in this respect), so the solutions involve either stand-alone lights or a camera-based light. Stand-alone lights are large and bright, often pointed at the ceiling to bounce light around into the room. These involve stands and cords that, when tripped over or knocked over, can present fire and safety hazards. Camera-mounted lights are usually attached to the top of the camera and the light is pointed straight at the subject.
