Lecture 15: Cameras & Lenses (81)

Does this mean that when rays converge at a point that is not the focal point, the image is stretched or compressed?


@CharlesLiu02, not the focal point, but 2 times the focal length away from th lens. Here's the formula: 1u+1v=1f\frac1u + \frac1v = \frac1f, where u and v are the distance from the lens to the real object/screen respectively.
