Digital Photography: The Missing Manual

Digital Movies

Movie making probably wasn’t what you had in mind when you bought a digital still camera. Even so, most cameras offer this feature, and it can come in handy now and then. Movie mode lets you capture QuickTime or AVI format videos (both kinds play on Windows and Apple computers) with sound included. You save the videos to your memory card right alongside your still pictures. Some cameras permit only 30 seconds of video per attempt; others let you keep recording until the memory card is full.

Most new cameras these days capture video with frame dimensions of 640 x 480—big enough to fill a TV screen on playback. Once you’ve transferred a movie to your computer, you can play it, email it to people, post it on a Web page, or burn it to a DVD. Just keep these pointers in mind:

• Know your memory. Digital movies, even these low-quality ones, fill up your memory card in seconds. Remember, you’re shooting 15 or 30 little pictures per second, which puts you in 512 MB, 1 GB, or 2GB card territory.

• Steady the camera. If you don’t have a tripod, put the camera strap around your neck, pull the camera outward so the strap is taut, and only then begin filming. The strap steadies the camera.

• Don’t try it in the dark. The flash doesn’t work for movies, so look for the best lighting possible before composing your shot.

• Set up the shot beforehand. Most cameras don’t let you zoom or change focus during filming.
