Overview

ISO 1007:2000 - Photography - 135-size film and magazine - Specifications defines mechanical, electrical and identification requirements for 135‑size (35 mm) cut film and daylight-loading magazines. The standard covers film dimensions, latent‑image frame numbering and digital bar-codes (DX system), magazine dimensions and bar‑codes, camera auto‑sensing areas, an information panel visible through camera windows, and mechanical strength and handling limits such as film pull‑out force and film‑spool attachment strength. It does not apply to bulk 35 mm film for reloading, reloadable magazines, or single‑use camera film.

ISO 1007 includes normative and informative annexes:

• Annex A (normative) - assignment of DX numbers
• Annex B, C (informative) - test methods and historical/design notes

Measurement conditions are specified (manufacture-time dimensions measured at 23 ± 2 °C and 50 ± 5 % RH; instrument calibration at 20 °C per ISO 1 and ISO 554).

Key Topics

• Film dimensions and leader/trailer/tongue geometry: standardized cut lengths (examples given for 12, 24 and 36 exposures), corner radii and critical tolerances to ensure reliable loading and transport.
• Perforation and cutting tolerances: precise positions and offsets for sprocket perforations used by camera transport systems.
• Latent‑image frame numbering and bar‑codes: specifications for dual‑track and optional single‑track latent‑image digital bar‑codes that encode the film’s DX number and frame numbering.
• Magazine dimensions and magazine bar‑code: standardized magazine size for daylight‑loading cameras and a barcode that encodes DX number plus number of exposures.
• Camera auto‑sensing areas (DX contacts): electrical and dimensional layout that allows appropriately designed cameras to read film speed (ISO/exposure index), number of exposures, and recommended exposure latitude.
• Information panel: visible film ID, speed and exposures through camera back windows.
• Mechanical limits: film pull‑out force and film‑spool attachment strength requirements to prevent damage during handling and transport.

Applications / Who Uses It

• Film manufacturers - to produce 135 film and magazines that are compatible with standardized cameras and photofinishing equipment.
• Camera and magazine designers - to implement auto‑sensing contacts, magazine fit, and window displays.
• Photofinishing labs and equipment makers - to read latent‑image barcodes and ensure accurate processing.
• Quality assurance and test labs - to verify dimensions, barcode encoding and mechanical performance per specified measurement conditions.
• Standards and procurement teams - to specify compliant 135‑size film products.

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.
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.
International Standard ISO 1007 was prepared by Technical Committee ISO/TC 42, Photography.
This third edition cancels and replaces the second edition (ISO 1007:1995) which has been technically revised.
This revision of ISO 1007 includes the following significant additions and changes:
a) A clause for definitions has been added in order to assist the reader of this International Standard in the proper
interpretation of the information presented.
b) A specification has been added for the single-track frame-number bar-codes, specifically the relationship of the
eye-readable frame-number to its bar-code.
c) In the dual-track frame-number bar-code system, encoding of frame numbers greater than 36A has been
incorporated.
d) The element width for the dual-track frame-number bar-code has been changed to allow element widths to be
“narrower” than in the previous edition of this International Standard.
e) The magazine bar-code system has been modified to allow for additional film lengths (digit 6), as well as a
change to digit 1 for additional flexibility.
f) Since part of 9.3 (DC electrical characteristics) was judged to apply to the test device (as opposed to the
magazine itself), it has been moved to informative annex B. It is now consistent with the philosophy that test
methods generally be documented only in informative annexes.
g) The text regarding how manufacturers shall be assigned DX numbers has been improved significantly. A new
method of using the magazine bar codes has been added to allow additional flexibility.
h) Several issues that were included in the informative annexes of the second edition of this International
Standard were judged to be obsolete. They have been removed in the interest of simplifying this revision, for
example, measurements and calculations for estimating the location of film edges and measurement of velvet
stiffness.
Annex A forms a normative part of this International Standard. Annexes B and C are for information only.

6 Latent-image frame numbering
Two sets of frame-number sequences, together with their location and orientation, are shown in Figure 1c).
The first set shall be provided on the edge nearest to the C datum plane (see Figure 3). It shall be numbered in a
half-frame series (1, 1A, 2, 2A, …, 36, 36A) with the numbers interspersed at four-perforation intervals.
A second set may be provided on the edge opposite the first set. If provided, it may be numbered either in a full-
frame series (1, 2, …, 36) at intervals of eight perforations or, if provided as part of the optional single-track latent-
image frame-number bar-code (see 7.3), it may be numbered in a half-frame series (1, 1A, 2, 2A, etc.).
Figure 3 — 135-size magazine bar-code (see Table 8)
7 Latent-image digital bar-codes
7.1 General
Latent-image bar-codes shall conform to the locations and dimensions shown in Figure 1 and given in Table 1.
A 23-bit dual-track latent-image bar-code, which identifies the manufacturer/film type using a system of DX
numbers (see normative annex A), shall be located on the edge nearest the C datum plane adjacent to each full-
frame and half-frame number on films designed for colour-negative processing. The bar-codes are visible only after
the film has been processed. When processed film is used with an appropriate film-code reader and an automatic
printer, colour printing can be optimized for each specific film so identified.
Frame-number identification may also be incorporated in different ways. One method is to expand the basic 23-bit
dual-track latent-image code by adding eight more bits for frame-number identification. Another method would be to
utilize a 13-bit single-track, modified 3-of-9, latent-image bar-code on the opposite film edge.
Use of latent-image bar-codes on 135-size films, other than those intended for colour negative processing, is
optional.
7.2 Dual-track latent-image bar-code
Each dual-track latent-image bar-code consists of adjacent data and clock tracks, each with the same number of
elements (23 without and 31 with encoded frame numbers). Each bar-element represents a digital binary bit, with
exposed elements (bars) representing a 1 bit and unexposed elements (spaces) representing a 0 (zero) bit, except
in the entry pattern (see 7.2.1.1).
7.2.1 Definition of the data track
The first reason for encoding information into the data track is to provide a unique DX number identification (see
normative annex A for information regarding the assignment of DX numbers). The DX number has two parts (part 1
and part 2). The two parts are used in combination to identify products. Part 2 shall not be encoded without part 1.
Part 1 is described in 7.2.1.2, and part 2 is described in 7.2.1.4.
The second reason for encoding information into the data track is to encode the frame numbers.
7.2.1.1 Entry pattern
The 6-bit entry pattern is used by the bar-code reader to detect the beginning of a code sequence. The final bit of
the entry pattern shall always be an unexposed element (space).
7.2.1.2 Identification array for part 1 of the DX number
The part 1 DX code has 7 bits. The 7-bit stream, starting with bit 7 and ending with bit 13, is used for encoding the
part 1 DX number assigned to a product in accordance with the procedure specified in annex A.
The sequences of exposed and unexposed positions that identify the 128 available part 1 DX numbers are given in
Table 3. (They are arranged in an ascending binary sequence for ease of referencing.) Dashes (—) in one of the
seven element position columns of Table 3 signify an unexposed element (space); a number signifies an exposed
element (bar). For example, the part 1 DX number 41 is encoded by the combination of unexposed elements
(spaces) in positions 7, 9, 11, and 12, and exposed elements (bars) in positions 8, 10, and 13.
Sensitizers may use a single part 1 DX number to identify a number of films that are designed for the same
chemical process.
7.2.1.3 Unassigned bit
The unassigned bit is in bit position 14 and shall be an unexposed element (space).
10 © ISO 2000 – All rights reserved

7.2.1.4 Identification array for part 2 of the DX number
The identification for part 2 of the DX number is 4 bits, starting with bit 15 and ending with bit 18. This 4-bit array
shall encode the specific part 2 DX number (specified in Table 4) that has been assigned to that product under the
procedure specified in annex A. Any individual location assigned as part of the part 2 DX number shall represent an
exposed element (bar). Dashes (—) in Table 4 represent an unexposed element (space).
The 16 possible combinations of this array are encoded as a 4-bit binary number, with bar position number 15
representing the most significant bit, and bar position number 18 representing the least significant bit.
7.2.1.5 Identification array for frame numbers
This optional 7-bit array may be added to encode whole and half-frame numbers in accordance with the patterns
given in Table 5. Bar positions 19 to 25 are a 7-bit binary representation of the frame number, with position
number 19 representing the most significant bit and position number 25 representing the least significant bit. Frame
numbers prior to the zero frame are derived by successive binary subtraction.
Bar position number 25 is exposed in those array’s that encode half-frame numbers. This is the half-frame “flag”.
Although the longest 135-size standard film length is 36 exposures, Table 5 provides the logical encodement for
frame numbers greater than 36A in case these numbers should be needed in the future.
7.2.1.6 Second unassigned bit
A second unassigned bit shall be included in bit position 26 only if the optional frame-number array is included. The
second unassigned bit shall be an unexposed element (space).
7.2.1.7 Parity bit
A parity bit shall be provided in bit position 19 in order to create even parity with data bits 7 through 18 inclusive.
(The total number of exposed elements [bars] in data positions 7 through 18, plus the parity bit position, shall be an
even number.)
Under the optional dual-track frame-numbering system, the parity bit is used to create even parity with data bits 7
through 25 inclusive and is located in bit position 27.
The unassigned bits are part of this consideration, but since they are always spaces they have no affect on the
count of bars for parity.
7.2.1.8 Exit pattern
The exit pattern shall be 4 bits as shown in Figure 1. It is used by a bar-code reader to detect the end of a code
sequence.

7.2.2 Clock track
The clock track shall be comprised of 23 bits if the data track does not contain optional frame-number encoding, or
31 bits if frame-number encoding is included in the data track. Each change in clock-track density signifies the
location of a data bit in the data track [see Figure 1e) and 1f) for specific locations of bars and spaces].
7.2.3 Quiet zones
Quiet zones shall be provided on both ends of the bar-code, as shown in Figure 1d) and as given in Table 1.
7.3 Single-track latent-image frame-number bar-code
The optional single-track frame-number bar-code consists of seven bar elements interleaved with six space
elements. Bar and space elements are either wide or narrow. Each element represents a digital binary bit, with
wide elements representing a 1 bit and narrow elements representing a 0 bit.
7.3.1 Definition of data patterns
7.3.1.1 Entry pattern
The entry pattern consists of one wide bar followed by one narrow space. It is used by a bar-code reader to detect
the beginning of a code sequence.
7.3.1.2 Frame-number sequence
The frame-number sequence consists of five bar elements interleaved with four space elements. There are three
wide elements (3-of-9) and six narrow elements in each of the valid frame-number sequences. The pattern for each
of the valid frame-number sequences shall be as given in Table 6, where a number in the bit column designates a 1
bit (wide element) and a dash (—) designates a zero bit (narrow element).
An optional end of roll sequence is provided for use at a location one full-frame pitch beyond the last full-frame
number bar-code sequence (frame number E in Table 6).
Alternative frame-number sequences are provided for the last full-frame and half-frame numbers to indicate end of
roll in 12, 20 and 24 exposure lengths. These alternative codes are marked with asterisks in Table 6.
7.3.1.3 Exit pattern
The exit pattern consists of one narrow space followed by one narrow bar. It is used by a bar-code reader to detect
the end of a code sequence.
7.3.2 Quiet zones
Quiet zones shall be provided on both ends of the bar-code, as shown in Figure 1g) and as given in Table 1.
7.4 Density specifications
The ISO standard status M red density of the unexposed elements (spaces) shall not exceed 0,50; the density
difference between an unexposed element (space) and an exposed element (bar) shall be a minimum of 0,50. For
additional information regarding status M red density, see ISO 5-3 ([2] in the bibliography).
The 690 nm density of the unexposed elements (spaces) shall not exceed 0,65; the density difference between an
unexposed element (space) and an exposed element (bar) shall be a minimum of 0,90.
These requirements apply to the processed film, assuming that the product has been kept under recommended
conditions before and after exposure, that the expiration date has not been exceeded, and that processing
conforms with established standards.

the spool is pushed so that the short-hub end is against the magazine end; that is toward the short-hub end.
Z max. applies when the spool is forced against the long-hub end of the magazine. The spool shall "float"
axially within the magazine, so that the film is capable of exiting the magazine at Z = 3,79 mm without
significant buckling or deformation in the focal plane.
b
In order to facilitate engagement with the camera key, the ends of the spool splines may be rounded.
However, such rounding should be accomplished within the maximums and minimums established for Z and
Z .
c
The rewind splines in the short-hub end of the spool may be either a solid or a split spline with the two
members separated by the distance Z .
d
The tangent lip of DX magazines shall be oriented parallel to the A datum plane to assure proper angular
orientation within the camera. This is preferred (but not mandatory) for non-DX magazines. Z is below the B
datum plane and for this reason is expressed as a minus value.
e
Dimensions Z is measured to the face of a gauge block that contacts the emulsion side of the film. In
practice, the magazine exit slot should be designed to present the film at this dimension. In no case shall the
film be presented less than 22,50 mm from the A datum plane by the time the film reaches the exposure gate of
the camera.
f
Dimension Z needs to be observed strictly only at both ends of the magazine, in order to guarantee a
radial guidance inside the camera. In the other area of the magazine wall, a smaller dimension, limited by Z ,
is allowed. The perimeter of the end cap shall have no sharp features that might damage the CAS probes of
the camera during loading; bottom loading cameras are especially vulnerable.
g
Radius Z can only be specified in terms of the maximum profile where the centre of this radius is at
Z =1,50mm, Z = 20,50 mm, and Z = 1,00 mm. These values, together with Z min. and Z max., are
