Overview

ISO 897:2000 is an international standard developed by the International Organization for Standardization (ISO) that specifies methods for identifying the image-bearing side of various roll films and 126, 110, and 135-size photographic films. This standard addresses edge markings as a means of identification, ensuring consistent handling, processing, and printing of photographic materials within the photography industry. The scope explicitly excludes cinematographic films, focusing solely on still photography film types.

Key Topics

• Edge Markings for Identification:
  ISO 897:2000 defines how letters, numbers (including frame numbers), words, and arrows can serve as markers to distinguish the image-bearing side of photographic films. These markings facilitate accurate film orientation and handling throughout various photographic workflows.

• Orientation of Marks:
  The standard prescribes the correct positioning and reading orientation for these markings, tailored to each film format:

  • Roll films, 126, and 135-size films: Markings are oriented so that numbers or letters are readable in the correct direction when viewing the processed film.
  • 110-size films: Sequencing and orientation are specified according to ISO 13450, with frame numbering increasing from right to left.

• Types of Markings:
  Markings may consist of:

  • Letters, words, numbers (for example, frame numbers)
  • Arrows indicating the progression of exposures and frame order
  • Combinations of the above for clear identification

• Practical Guidance:
  The standard provides recommendations on the quantity, placement, and orientation of these edge marks, supporting uniformity across manufacturers and users worldwide.

Applications

• Film Manufacturing:
  Film producers use this standard to ensure films are consistently marked, enabling photographers, labs, and end users to identify the correct side for exposure and processing.

• Photographic Processing:
  Processing labs rely on these markings to load unexposed films and handle processed negatives or slides accurately, minimizing errors during development and printing.

• Camera Design and Usage:
  Camera manufacturers and photographers benefit from standardized film markings, which contribute to proper film loading and exposure.

• Archival and Cataloguing:
  The clear identification of the image-bearing side is vital for archival storage, labeling, and retrieval of photographic materials in collections and libraries.

Related Standards

• ISO 13450:1996
  Photography - 110-size cartridge, film, and backing paper - Dimensions. This standard details dimensional specifications essential for interpreting 110-size film markings.

• ISO 732:2000
  Photography - 120-size and 220-size films - Dimensions. Offers size-related guidelines for other common photographic films, providing consistency across different formats.

• ISO 1007:2000
  Photography - 135-size film and magazine - Specifications. Specifies the properties and measurements related to 135-size film cartridges and magazines.

• ISO 3029:1995
  Photography - 126-size cartridges - Dimensions of cartridge, film, and backing paper. Details the physical characteristics relevant to 126-size film, complementing the identification practices set by ISO 897:2000.

---

ISO 897:2000 supports accuracy and efficiency in film handling across the photography industry by standardizing image-bearing side identification for key film types. Adhering to this standard enhances consistency, reduces mistakes, and facilitates seamless integration with related ISO standards for photographic materials.
