Instructable user fpound of kontent films needed to take a really long time lapse. How long? 4 months – to show water changing over a season. While any battery will last for a night time lapse, running for four months is not only battery heavy, but it calls for camera protection against the elements.
Here is a video that shows the power of taking a timelapse over an entire season.
Setting up a camera to such a long duration requires quite a bit of preparation, but pfound made a point of documenting those preparations providing very clear and easy to follow instructions.
The process involves several steps:
Securing the camera with a Pelican case. The case provides a housing for the camera, battery and intervalometer.
The case is fitted with a pipe for the lens and a clear UV filter, making it practically a weather sealed tank proof home for a camera.
Power is coming from a 12 volt car battery running through a power converted and a faux battery.
Finally an intervalometer is hooked up and set to the desired interval.
Last but not least, you definitely don’t want anyone calling the cops after seeing a weird box making clicking sounds. so clearly explaining what you are doing is a good idea:
