CLASSIFICATION MARKINGS ON
IMAGING PRODUCTS
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
14-3
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 repro-
ductions 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.
DISCLOSURE OF CLASSIFIED MATERIAL
When classified matter is entrusted or made known
to you, you must protect it against loss or compromise.
You are responsible for any act or failure that contributes
to the loss, compromise, or unauthorized disclosure of
classified information. This includes information that is
passed verbally.
When you are found responsible for the loss,
compromise, or unauthorized disclosure of classified
matter or when you violate security regulations, you can
expect to be disciplined promptly. Disciplinary action
may include, in the case of military personnel, trial by
court-martial or, in the case of civilians, prosecution
under Title 18, United States Code, as amended, or other
federal statutes, as appropriate.
PROTECTIVE MEASURES
Generally, there are four ways that classified
information is protected: censorship, physical security,
transmission security, and cryptographic security. As a
photographer, you will be concerned primarily with
personal censorship and physical security.
Personal Censorship
Censorship places a barrier between classified
information and unauthorized personnel by preventing
disclosure in the form of letters, conversations, and
personal contacts. Restricting information at the source,
except for official use, depends on the integrity and
discretion of the individual.
