The third consideration for getting good results in your shoot is camera support. There is no quicker way to induce motion sickness in your audience than hand-holding your camera for the entire shoo; get a tripod! . And if you want smooth tracking motion while you are following a subject, or to create motion in an otherwise static product shot or interview, you'll need a slider or a dolly.

You can buy a cheap tripod for around $20, or you can rent a more quality setup with a pan-and-tilt head for smooth panning shots like the one at Borrowlenses here for ~$50 for 3 days
