Good responses here. Part of it is that a transparent image, lit from behind, can reproduce a *much* finer range of detail, and wider range of brightness, than an opaque image lit from in front…that’s why slide projection is popular in color photography.
Med students spend a *lot* of time learning how to tell one object from another in an X-ray…every faint, subtle line means something.
