Composing Your Shots


Home Video Hints: Composing Your Shots

Shooting great looking video can be as simple as solving a few problems with composition.
The key to good-looking video is a well-composed shot. What exactly is composition? Technically, composition is the relationship between two or more objects in a picture, where one of the objects shows dominance. This involves careful placement of your subject in your shot so that it looks good and grabs the attention of your audience. In this column, we will provide a list of common composition problems and their solutions.

Shaky Shots

Problem: Your footage is shaky and difficult to watch.
If you have to hand out Dramamine before showing your videos to friends, you might suffer from shaky cam syndrome. Tromboning (using the zoom too often like the slide of a trombone), hosing (panning the camera back and forth like a fire fighter) and constant stopping and starting movements all are symptoms of this problem.
Solution: Compose a shot, roll tape and hold still.
You should always compose your shots before you push the record button. Once you press record, hold the shot for at least five seconds before moving the camera. If you do have to move the camera or zoom, do it slowly and deliberately without stopping until the movement is completely done. Always know where you want to move the camera next, and plan your moves before you make them. It is easier to hold wide shots steady than telephoto shots. For best results, zoom out to the widest angle your lens permits and move closer to your subject.

The Slippery Slope

Problem: Your shots are tilted, making your subjects look like they might slide out the side of the picture.
This problem is obviously caused by the camera being tilted sideways at an angle. It doesn't have to be a very big angle to distract your viewers. Is the water in that gorgeous sunset over the lake running out of the side of your shot? If so, you may be sliding down the slippery slope of composition.
Solution: Check your horizontal and vertical surfaces in the shot to make sure the picture is level.
The real key to this solving this common error is to pay attention to the frame while you shoot. Find a building, doorway or some other straight and vertical or horizontal object and use it as a guide to keep your picture straight and level. If you are shooting a horizon, especially one with a perfect edge like a lake or the ocean, line the surface up with the top or bottom of the viewfinder and then carefully tilt back to compose your shot. Try to place your horizon on the top third of the picture or the bottom third depending on what is more important, the sky or the foreground. Never depend on the leveling bubble on the tripod, which only shows the tripod to be level and doesn't account for the parts of the tripod and camera above the level. Therefore, you should only use the leveling bubble as a quick reference point.

Manual Focus


Getting Started: Manual Controls

Sometimes it pays to be a control freak
Automation is nice. Heat sensing microwaves that can tell how long to heat leftovers, say, are very convenient. But sometimes you need to override the automatic settings to cook things just the way you like them.
The same holds true for camcorders. While most camcorders automatically adjust the focus, audio levels, shutter speed and iris to ambient conditions, your videos might look better if you override some of your unit's features and take control of your shots.
But with everything set automatically, why bother? Well, you may encounter situations where your camcorder, for all its technological wizardry, just can't make heads or tails of what's going on. Or you may want to create a visual effect that goes against the grain of your camcorder's automatic sensibilities.
In any case, taking control of your camcorder's functions is simple enough.

Manual Focus

Generally speaking, your camcorder determines focus by finding a well-defined object in your frame--typically whatever is in the center of your shot--and using that as a reference point for deciding how to focus.
Regardless of how handy autofocus can be, there are situations when your camcorder finds it difficult to locate the subject of your shot. When there's not enough light, perhaps at night or in a dimly lit room, objects tend to blend into one gray mass as far as the camcorder can tell.
Your camcorder, desperately trying to locate the subject of the shot, goes in and out of focus rapidly. With manual control, you can use your eye, which is infinitely more sensitive to light than your camcorder, to focus the shot instead.
Manual focus allows you to add certain effects to your video. For example, there is a manual focus technique called rack focus that camera operators use to bring the foreground and background alternatively in and out of focus. Racking focus allows you to direct the viewers' attention within a given shot by focusing on different objects successively, each time blurring the other parts of the shot.
You've probably seen this technique in a movie or television program: a close-up shot of the telephone, sitting on the edge of the desk, ringing off the hook. The background is blurred just enough to obscure it. The camera operator then slowly shifts focus from the telephone to the background where a man sits in an easy chair. As the man comes into focus, the phone blurs.
You may want to blur your shot as a segue from one segment to another. You can create a unique transition from shot to shot by ending and beginning each shot out of focus. One gray blur looks pretty much like another; by blurring your shots this way, you can cut from shot to shot creating an interesting in-camera transition effect.
How do you switch from auto to manual focus? Most units have a button somewhere on the camcorder that will toggle autofocus on and off. You'll have to consult your manual for the specifics regarding your camcorder.
The convenient thing about autofocus is that when you turn it back on, your shot will automatically focus itself. This is useful if, as I described above, you want to begin your shot blurry and rapidly bring it back into focus. Use manual focus to blur your subject first, then after a few seconds of recording the blurred image, turn the autofocus back on again. Your subject will come into sharp focus as your camcorder takes over for you.
