Vello Two-Axis Hot-Shoe Bubble Level

This Two-Axis Hot Shoe Bubble Level from Vello mounts onto any standard hot shoe on a camera. It allows you to precisely align the camera on two planes, to ensure that the horizon line is absolutely straight. This is a necessary accessory for QTVR shooting sessions, for landscapes, or any other photography requiring fidelity to a horizon line or other straight-line elements.
