When inspecting positive or negative film or slides for content (what the picture shows) or condition (possible wear and tear), a Peak magnifying loupe and a lightbox are the easiest tools to use. The practitioner places film on the lightbox, which has a translucent cover and low-heat fluorescent lights, positions the loupe over the portion of film she wants to see, and puts her eye right above the magnifying lens to look down at the film. The result might be what you see here at right.
