Part III: Section B
Building a Photographic Frame
4. Steps 5-6

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.

Step 6: Inserting the 90° Connectors to the Quadrat to Hold the Upper Part
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.

Insert the slip tee connector so that the open end is facing upward.


Make sure the length of each side is still 1 m, then reinforce the quadrat with screws.
