Equipment for the film production
In addition, the equipment used in the production is essential for the quality of the footage. This includes lighting, grips (e.g. tripods), and the sound equipment.
For a business film, you should always insist on additional light. Even though modern cameras are that sensitive that the most locations are sufficiently illuminated, the use of additional light is indispensable. Lighting is used for composition, creation of atmosphere with coloured light, and guidance of the viewer’s attention through contrasts. In the most basic case the camera operator uses a so called headlight, which is fixed on the camera and is normally used for the lightening of close ups. A sole headlight will only be used in situations, when composition is not possible. The minimum standard is a lightning set with halogen lamps (between 500 and 800 watt). A higher quality production will also utilize Dedolights and a so-called HMI-light (a very bright light which produces daylight).
The simplest case the camera is fixed on a tripod to provide for a stable shot. A roller stand unit makes it possible to do simple horizontal movements. A variation is the “Slider”, a short rail which is normally fixed on two tripods and that enables smooth linear movements. More complex movements are possible with a Dolly. There the tripod is fixed on a “wagon” which is moved on either air wheels or rails. The combination with a jip-arm (a small crane) allows to move the camera vertically. Bigger vertical movements are possible with a camera crane. A special case is the Steadycam. The camera “hovers” on the cinematographer and therefore uniquely smooth and flowing movements are possible, but the handling needs a lot of experience.
The third important part is the sound equipment, which is often neglected at non-professional productions. In particular, selection of microphones and sound modulation should avoid camera integrated solutions and utilize an external sound mixer instead.
