Time-Lapse Cameras are really fun to use. Probably most well known for Construction Time-Lapse Photography where you see a fast forward film of a building being constructed in a few simple minutes, or a timelapse camera being left facing the night sky to record the movement of the stars turning hours into seconds on playback.
How does it work?
Decide on your project, maybe it's a shed being built, turning a piece of land into a wildlife area or making a pond, growing a plant or monitoring the change in seasons, It really doesnt matter if its hours or weeks. Set the time-lapse camera to take a picture every hour, day or every minute for short term projects, the important thing is that the timelapse camera must not move whilst recording. When you've finished the project you can easily stitch all the photos together using software to make a time lapse video, just like flick book images really!
