Reproducible, Durable and in Standard Sizes.

Standard IV. Documentation Shall be Clearly and Concisely Produced...

...legible and understandable, and... must contain scale information and location

references.

5x7 = 35 square inches

35mm = 1.5 square inches

Large format B&W film is silver on polyester

Size does matter

Size = ResolutionStable 500+ years

More durable – heavier film baseSheets of film easier to handle, label & catalog

Few digital preservation success stories – many horror stories!

High cost of high-resolution digital cameras & equipment(Replacement 3-5 years)

IT Digital storage costs are approximately TEN fold.

NARA archives = $5m for analog archives ($80m and $50m for ERA)

No standards exist for BORN-DIGITAL archival photo surveys

HABS/HAER/HALS would need to establish those new standards
