The Brinno TLC100 time-lapse camera is a very simple device that aims to simplify time-lapse photography as much as possible. There are many ways to take time-lapse videos. You can use any digital camera or any video camera. The difference with a dedicated time-lapse camera like the TLC100 is it takes out a lot of the work that needs to be done such as stitching still images together and creating the video file.
With the TLC100 (currently $135 at Amazon) you simply point the camera where you want, choose your time interval (anywhere from 5 seconds to 24 hours) then press a button and walk away. When you stop it, you will be left with an .AVI file of your time-lapse.
