I read through the page on depth of field, and their was one thing that couldn't understand was what would happen if you took a picture of someone through a mirror. If I take a picture of a mirror and the focal plane exactly matches the reflective surface of the mirror, will everything reflected in the mirror, regardless of distance, come into equal focus? Logic would dictate that since all the light reflects off the mirror at the same distance from imaging plane of the camera, all objects in the frame are effectively the same distance from the camera. What happens in practice?
