When shooting time lapse, different situations and climates require special housing designs. I used these water proof housings for this Extreme Makeover time lapse.
I used Storm cases for the outer shell. These have o-rings and are completely waterproof and light.
A precision camera sled was leveled and installed on the bottom of the housing. This gave me total access to the camera for changing cards or adjustments. A U-bracket was attached and provided tilt and swing to the housing.
