Every picture find shows the clear section on the bottom with the canon logo right side up, which means it goes where the black tube is. But you don't actually want to do that for viewing slides since you want to light slides from behind which means you want the black tube and not the transparent one. The transparent one is for viewing stuff like prints where you have to let the room light in so that it's not just shadow
