HemiView Camera System

The HemiView V8 system demands that the camera, mounting, stabilization are all integrated into a professional package for field environments. Our years of experience led to the creation of this affordably priced high quality package with the latest in Digital SLR technology.

HemiView is a state-of-the-art program that processes hemispherical images to provide information about plant canopy geometry and sky obstruction.

Photographs are taken looking upwards from beneath the plant canopy, or from the forest floor, using a 180° fish-eye lens and digital camera. Lighting conditions with uniform sky illumination are required, such as an overcast sky, or just before sunrise or after sunset. The camera is mounted in a self-leveling mount, which holds the camera level at whatever the mounting angle. It also provides reflective markers for the North-South axis, both essential to accurate alignment of the image later.
