BRIEF HISTORY
The IS0 Recommendation R 515, Dimensions for Stereo Still Photography Using 35 mm
Objectives on 35 mrn Film, Five-Perforation Format, was drawn up by Technical Committee
ISO/TC 42, Photography, the Secretariat of which was held by the American Standards Association,
Inc. (ASA).
Work on this question by the Technical Committee began in 1955 and led, in 1960, to
the adoption of a Draft IS0 Recommendation.
In August 1961, this Draft IS0 Recommendation (No. 422) was circulated to all the IS0
Member Bodies for enquiry. It was approved by the following Member Bodies:
Belgium Italy Switzerland
Brazil Japan United Kingdom
Canada Netherlands U.S.A.
Chile New Zealand U. S. S. R.
France Romania
Germany Sweden
No Member Body opposed the approval of the Draft.
The Draft IS0 Recommendation was then submitted by correspondence to the IS0 Council,
which decided, in November 1966, to accept it as an IS0 RECOMMENDATION.

IS0 Recommendation R 515 November 1966
DIMENSIONS FOR STEREO STILL PHOTOGRAPHY
USING 35 mm OBJECTIVES ON 35 mm FILM,
FIVE-PERFORATION FORMAT
FOREWORD
It is intended that this IS0 Recommendation, although restricted to cameras with 35 mm focal
length objectives, should also be used as a guide, with respect to type of information considered
essential, for other IS0 Recommendations pertaining to stereo photography systems.
1. SCOPE
L
This IS0 Recommendation specifies the dimensions of the picture apertures in stereo still cameras
using lenses of 35 mm focal length and producing the five-perforation format on standard,
double-perforated 35 mm film. It establishes the dimensions of the related mounts and mounting
requirements for both hand-held viewers and projection viewing conditions. Certain camera
design aspects essential for satisfactory stereography are also specified.
2. TRANSPARENCY DIMENSIONS
2.1 Camera aperture dimensions are determined by measurement of films after exposure in the
camera. The following dimensions and tolerances are required :

2.2 The centerline of each picture frame should pass through the centerline of a film perforation
within i 0.75 mm (+ 0.030 in).
2.3 The picture frame produced by the right-hand lens (when the camera is in operating posi-
tion as viewed from the back of the camera) should be identified by some mark exposed on
the film simultaneously with the picture exposure.
3. CAMERA ESSENTIALS
The camera objective lenses, which have a focal length of 35 mm, are displaced one toward the
other by 0.58 mm (0.023 in) with respect to the centerline, of their apertures.
4. STEREO MOUNT DIMENSIONS
The dimensions shown in Figure 2 apply to all stereo mounts. In Figure 3 are given the critical
dimensions for stereo mounts for hand viewing and for three different conditions of projection
viewing.
