A dolly zoom, also known as a Hitchcock zoom, is a technique that has the camera dolly in toward a subject while zooming out in the opposite direction (or vice versa). The effect can be quite jarring because it keeps the subject’s size the same relative to the frame while the background changes. The dolly zoom is often used in horror movies or thrillers because it is so shocking visually. Alfred Hitchcock uses it very often (see Vertigo), and it appears in Jaws as well when Chief Brody (Roy Scheider) is stunned by the shark attack at the beach. Although a useful technique to know, the dolly zoom should not be overused and must be practiced thoroughly.

A jump cut is an editing term referring to an abrupt break in a continuous shot, most noticeably when a moving object appears to jump within the frame. Take the example of an interview. After shooting what you need, you may notice that your subject’s answer is long-winded and you only want certain parts. However, the subject maintains the same basic position within the frame the entire time. If you cut from one part of his answer to another, his head or hands will appear to jump in the frame as he moves them while speaking. To fix this, one solution is to use a cutaway shot. Literally, you cut away from the primary shot of your subject to a secondary shot like a close-up of his hands. This way, you can cut back to the rest of the subject’s answer without seeing him jump.

It never hurts to be too safe, especially when you're working with expensive equipment. On a set, always tape down your cables so they don’t trip up your subjects or crew. In addition, make sure your century stands (for holding lights) are stable and not in danger of falling. As for electronics, never overload an outlet, especially when you are using high-powered lights. If you only have one outlet, use a surge protector and try to minimize the appliances plugged in.

Camera angles can play a huge role in how you represent your subject or setting. Generally it is best to keep the camera at eye level when shooting a person, but alternative angles can yield interesting psychological effects. Shooting a person from above (high angle) makes him/her appear smaller or low in stature – and thus weak or even submissive. Shooting someone from below (low angle) creates the opposite effect, making a person seem powerful or overbearing. Try to incorporate a variety of shots from different angles in your work.
