These two sets of image planes are found at the following points:
Objects far away from the camera then produce sharp images on the sensor or film, which is also at the image plane.
An image plane where the 3D world is projected through the aperture of the camera.
A point R at the intersection of the optical axis and the image plane.
In this approach, each of the 4 edges of the image plane is tested at a time.
When a camera is used, light from the environment is focused on an image plane and captured.
Dust on the image plane is a constant issue for photographers, and especially so in digital photography.
However, the right camera sees this line as a line in its image plane.
The entire subject can be in focus, even if it is not parallel to the image plane.
Repeat steps (3-7) for each point in the image plane.
