During a conference call, it can be difficult to position multiple people in such a way that everyone is actually in-frame.
- Only one person fits into the frame, or:
- Everyone is extremely far from the camera, so 95% of the screen area is taken up by a conference table.
Figure 1 illustrates this common scenario.
An inexpensive prism can fix this problem once and for all (Figure 2). A prism can be placed directly in front of the camera to split the image into multiple horizontally-spaced parts.
Now everyone can participate in the conference call without needing to move the camera around!
PROS: Encourages conference call participation by people other than whoever happens to be directly in front of the camera.
CONS: Might result in an unflattering “fun house mirror” effect in the final image. (Although this could be fixed in software, or by a more complicated prism setup.)
