Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
The main task of technical committees is to prepare International Standards. Draft International Standards adopted
by the technical committees are circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 2907 was prepared by Technical Committee ISO/TC 36, Cinematography.
This third edition cancels and replaces the second edition (ISO 2907:1984), which has been technically revised.

INTERNATIONAL STANDARD ISO 2907:2002(E)

Cinematography — Maximum projectable image area on 35 mm
motion-picture film — Position and dimensions
1 Scope
This International Standard specifies the maximum dimensions of the film image area intended for projection from a
35 mm motion-picture film and the position of this area relative to the perforations and the reference edge of the
film.
This International Standard specifies three types of image areas intended for theatrical projection (see A.4 in
informative annex A):
 Style A: general theatrical release prints commonly referred to as non-anamorphic or wide screen;
 Style B: theatrical release prints with an anamorphic image;
 Style C: classic theatrical prints.
2 Position and dimensions of image area
The dimensions shall be positioned as shown in Figure 1, and as specified in Table 1.
NOTE 1 Dimensions B, D, and E define the image area on the film that is available for projection. They do not define the
opening in the projection-aperture plate. The size of this opening may differ from dimensions A and B, for example, because of
the physical separation necessary between the aperture plate and the film to avoid scratching the film, the slant of the marginal
rays accepted by the projection lens, etc.
NOTE 2 It is recognized that, in many cases, the actual film image area that is projected may be smaller than the projectable
maximum and, in some cases, may be non-rectangular (for example, an irregu
