- If the camera is turned (rotated) about the focal distance, would
- not the apparent DOF proportions be dependent on the amount of
- perspective present?
- For example, if the Zoom Factor were set to a very high value to
- simulate an orthographic view, the DOF proportions would be
- approximately 50/50... no?
