Step 5: Building the Vertical Component
To create the vertical component of the photographic frame, the height needs to be measured. For a 28mm lens, the camera should be set 1.7m (5.5 ft) above the ground to capture an image showing a 1m 2 quadrat area. Other lens sizes may differ, so when building a frame, this needs to be taken into consideration and possibly adjusted. To start, cut the vertical PVC pipe segments, as well as a 1m-long crossbar that will be connected to the tops of the two standing pieces, situated parallel to the ground. Using 90 o connectors, connect the 1.7m sides to the 1m crossbar to form the camera frame, as shown below.

On two opposite sides of the quadrat, insert two slip tee connectors so the vertical sides supporting the camera can be fitted, as demonstrated in the figures below. Due to the pipe width, a gap should be cut out of the quadrat, which should be shifted from the mid-point. This adjustment accounts for both the camera and the pipe width.
