The previous blog discussed the use of an intervalometer with a DSLR in order to create time-lapse video. The process is simple if approached correctly but there are a few things to consider. First is interval—the time between exposures. Most intervalometers used with DSLRs have a minimum interval time of one second. A fraction of a second interval is not possible. With a playback time of 30 frames per second, one minute of real time goes by in two seconds of time-lapse—thirty times real time.

Interval Settings

Time-lapse apps such as Framlapse Pro for Android phones offer intervals as brief as one tenth second or three times normal speed. Yet smartphones do not have the exposure adjustments of a DSLR. Time-lapse on a smartphone can be fascinating. But a DSLR offers definite advantages depending on what you want to accomplish.

Exposure

Exposure time is also an important consideration, long exposures often being the preferred choice. Moving traffic at night is a common subject that takes a long exposure to create the characteristic streak of light. Consider this time lapse of traffic shot in daylight and the same scene at night.

The exposure at night was one half second at a two second interval. The streaking light trails make a much more appealing time lapse. Check out this article for further instruction on the proper use of time lapse.

Of course a major element of successful time lapse video is a sturdy camera support. If no tripod is available, any solid object can serve as a camera support just by holding HandlePod against it or securing it with the elastic cord. HandlePod makes time-lapse easy with a minimum of weight and bulk.
