The requester of imaging products determines the security classification of the product according to the guidelines contained in OPNAVINST 5510.1. Each original and all photographic copies that are classified must be marked with the appropriate security classification, the classification authority, and declassification and downgrading instructions based on the original classification markings.

Photographic film, prints, and slides that are classified must be marked with the appropriate classification and other applicable markings.

Film

Roll negatives are marked on the base side with the classification and associated markings at the beginning and end of each strip. Single negatives cut from the roll or single- sheet film negatives must also be appropriately marked on the base side. These materials must be kept in envelopes or film canisters with conspicuous markings.

Transparencies and Slides

The classification and associated markings must be shown clearly on the slide mount or transparency frame and whenever possible on the image area. Because the classification on 35mm slides are not conspicuous until they are projected, the classification must be marked on the slide mount. It is not necessary for each transparency of a set of transparencies to bear applicable associated markings when the set is controlled as a single document. In such cases, the first transparency bears the applicable associated markings.

A camera that contains exposed film of a classified subject must be given the same protection as the classified subject. Be cautious with Polaroid film when photographing classified material. All waste products produced by these films must be destroyed as classified waste.

Prints

All 8x10 and larger prints must be marked with the classification at the top and bottom of the face side with the associated markings at the bottom. On smaller prints the classification is required to appear only once on the face side. When it is not practical to place the classification and associated markings on the face side

of prints, the markings can be placed on the reverse side, using a pressure tape label or a stapled strip when stamping is not practical. All photographic reproductions must show the classification and associated markings clearly.

Motion-Media Products

The beginning of each reel of film or videotape must be marked with a title that bears the classification and associated markings. These markings must be visible when projected on the screen or played through a monitor. Only the overall classification is required at the end of the reel or videotape. Reels and cassettes must be marked with the appropriate classification and kept in containers that are marked conspicuously with the classification and associated markings.
