Customer needs:

  • create a digital copy because the source item is a high risk for loss of information (usually due to deterioration or obsolescence), and/or
  • exhibit or other researcher purposes require a high quality copy

Product solution: The final product should be at high-to-maximum information capture standards that capture a high degree of visual information beyond just the content and satisfy long term preservation needs.
  • This file is placed in a managed storage environment and retained for the long term.
  • This file satisfies both long term preservation needs and researcher requests for high quality files.
  • Because of the high capture specifications, this file could confidently take the place of the original record if the original record is no longer viable.
  • To ensure sufficient usability of the copies created from aerial film, special attention is paid to maintaining dimensional accuracy.
  • This file can make other files including exhibition quality files, reproduction masters and distribution copies.
Preservation Master:

If this product category is needed, the specification is determined by the size of the source material.
Smaller than 8x10
Aerial Print Maximum - 4000 Line

[AEP-P1]
8x10 and up to and including 11x14
Aerial Print Maximum - 6000 Line

[AEP-P2]
Larger than 11x14
Aerial Print Maximum - 8000 Line

[AEP-P3]

Customer needs:

  • create a digital copy to minimize risk due to frequent handling or high use (but not address high risk of information loss due to deterioration or obsolescence), and/or
  • improve access options.

Product solution: The final product should range from minimum-acceptable to less than high-to-maximum information capture levels to satisfy limited risk and access needs by capturing the content of the image but maximum quality levels are not needed.
  • This file is placed in a managed storage environment and retained for the long term it represents a significant time and resource investment and/or is part of a coherent set. If the file can be regenerated from a preservation master with minimum effort, it is usually not managed and retained.
  • This file satisfies most researcher requests as well as limited preservation risks including loss, theft, and mishandling.
  • Because the capture/transfer specifications are closer to or at the minimum recommended level, this file would not be an optimal substitute for the original record if the original record is no longer viable.
  • This file can be generated from a preservation master or be the highest quality file created in a project.
  • This file can make other files including distribution copies.

Definition of coherent set

To ensure sufficient usability of the copies created from aerial film, special attention is paid to maintaining dimensional accuracy.
Reproduction Master:

If this product category is needed, there is only one specification regardless of the size of the image.

Characteristics of the original object are not a factor in the product specifications.

Digital Options from Master File

Customer needs:

  • create digital files for specific distribution and access systems from a preservation or reproduction master file, and/or
  • there is no reason to retain the files after the distribution or access goal is met.

Product solution: The final product should meet the file requirements of the specific delivery systems. In general, these products emphasize small file sizes and faster transfer rates over high quality levels.
  • This file is retained only as long as needed to satisfy a specific distribution need. It is not actively managed over a long term.
  • Other files would not be generated from this file.
  • This file is not intended to substitute for the original record if the original record is no longer viable.
Distribution Copies:

If product category is needed, choose one or more as appropriate to suit project needs.

Characteristics of the original object are not a factor in the product specifications.

Hard Copy Option

Customer need:

  • Create textual or photographic prints from preservation or reproduction masters (or other supplied digital files) for specifically identified purposes.

Product solution:Create high-quality facsimile prints for exhibit needs or specific requests, or producing reference prints for a variety of project needs.

This product is not retained.

Distribution Copies:

If product category is needed, choose one or more as appropriate to suit project needs.

Characteristics of the original object are not a factor in the product specifications.
