ISO 1754:2010

Overview

ISO 1754:2010 is an international standard published by the International Organization for Standardization (ISO) that specifies the dimensions of picture sizes for cameras using 35 mm film and roll film. This standard applies to still photography cameras where the image size is defined by the camera frame. It provides clear and consistent measurement guidelines for the dimensions on film of various picture formats, ensuring uniformity and compatibility in photographic equipment and media.

Notably, ISO 1754:2010 does not include panoramic image dimensions, such as those from mid-roll panoramic cameras with formats like 13 mm × 36 mm. The focus remains on standard still picture sizes widely recognized in the photography industry.

Key Topics

• Picture Size Dimensions
  ISO 1754:2010 defines specific nominal dimensions for various film sizes and formats, including:

  • 18 × 24 mm
  • 24 × 36 mm (standard 35 mm format)
  • 4.5 × 6 cm
  • 6 × 6 cm
  • 6 × 7 cm
  • 6 × 9 cm

• Dimension Tolerances and Radii
  The standard details maximum tolerances allowed on dimensions as well as the corner radius for picture sizes, which is critical for ensuring accuracy and quality in film manufacturing and camera framing.

• Film Size References

  • 135-size film (35 mm film) dimensions are referenced through ISO 1007.
  • 120-size and 220-size roll films follow specifications detailed in ISO 732.

• Applicability to Cameras with Interchangeable Lenses
  For cameras with interchangeable lenses, the specified picture size refers to the image produced using the camera’s standard lens, providing a baseline for standardization.

Applications

ISO 1754:2010 serves several practical purposes within the photographic and optical equipment industries:

• Manufacturing Consistency
  Camera manufacturers use this standard to design frames, viewfinders, and lenses that correspond accurately to standardized film image sizes.
• Film Production Quality Control
  Film producers adhere to these defined dimensions to manufacture film stock that fits camera specifications perfectly.
• Interoperability Among Brands
  By standardizing picture size dimensions, photographers and professionals can rely on compatibility across various types of cameras and films.
• Photography Calibration and Testing
  Laboratories and developers reference these dimensions to calibrate equipment and verify image outputs from different camera and film combinations.

Related Standards

ISO 1754:2010 works alongside other ISO standards to support full coverage of photographic equipment and film specifications:

• ISO 1007 – Photography - 135-size film and magazine - Specifications
• ISO 732 – Photography - 120-size and 220-size films - Dimensions
• ISO 1203 – Photography - Roll film cameras - Back window location

These standards collectively ensure comprehensive standardization across film types, camera formats, and handling procedures important in analog photography.

By adhering to ISO 1754:2010, manufacturers and users in the photography sector benefit from internationally recognized dimensions for still picture sizes on 35 mm and roll films, contributing to quality assurance, compatibility, and the overall evolution of photographic technology.
