The video above is an awesome example of what you can do with your DSLR and Timelapse photography. Timelapse photography is where you can set your camera to take a photo every so many seconds, or sometimes even minutes. Next just drag all the photos into a video Timeline and export as a video clip. In Sony Vegas, I often run each photo at 0.065 seconds on a 29.97 Timeline. In order to achieve timelapse function with your DSLR you will need a ‘timer’ or ‘intervalometer’. It's rare to find cameras that have built in Timelapse, and if they do, it might not be as flexible as having an exteral Intervalometer. Here's a great option that less than half the price of OEM if you're a Canon user.
