How do digital cameras work?

Austin asked:


I really have two questions. One is about how digital cameras actually capture images and create image files. The other is about how cameras end up taking rectangular pictures. I mean, if you look at cameras. the lenses are circular, so how do they end up taking rectangular pictures, and why? Why are movies and photos always square, rather than circular?

   well;; yes the LENS are circular. but the object inside the lens that actually captures the photo inside is a square, rectangular shape. the lens are circular so that the camera could get a 360 degree look at the object that the camera is capturing.
