This guide shows how to make a protective case large enough for two synchronized cameras, when you are taking infrared and regular photos from a balloon mapping setup.

We'll be using 1 gallon Tropicana orange juice jugs

Start by slicing the bottom off of a 1 gallon Tropicana orange juice jug

Holding the rig upside down, lower the cameras into the bottom until they rest against the "shelf" formed by the handle. Pull the tether string out through the mouth of the jug and, holding it taut, close the jar over the string. Center the string so that the jug hangs without tilting to one side.

The jug should be sturdy, but if you're worried, you can tie a second tether around the handle. Just don't stop the first tether from hanging straight or the whole rig will tilt to one side.
