The Brinno TLC200 is a new class of camera designed to make HD time lapse photography simple, yet it has the flexibility to change lenses and custom program time intervals for the serious time lapse movie maker. The TLC200 has advanced power management, providing months of battery life for extended duration capture periods. It even has an optional external shutter release for creating stop action movies (model ATS100 Shutter Release Cable sold separately). The 1.44 inch LCD preview screen allows for accurate targeting of subjects and precise framing of scenes. The interest in time lapse photography has been growing steadily in recent years, as shown by the vast numbers of time lapse movies being posted to video sharing sites. In the past the user had to use an expensive digital camera making the camera unavailable for normal use while making the movie; but not any longer. To use the TLC200, simply turn it on, set a time interval, aim the camera and wait for the video to finish. The TLC200 can be mounted on a tripod or simply set on a flat surface.
