Action Plan: Tagged Image File Format - UNC Encoding

Last Updated 2/5/2014

Description: Tagged Image File Format, or Tiff files, are some of the most common Raster Image Formats in use. Created by the Aldus Corperation which was later aquired by Adobe, Tiff'stechnical specifications have been released by Adobe. It was last updated in 1992, its current version is 6.0.

Codec:  The TIFF UNC encoding is often used by digital library projects to make masters. It is uncompressed with Exif Metadata.

Software:  Tiff is supported by all major browsers and image manipulation software suites.

Long Term Preservation Plan:  Uncompressed Tiff is the prefered format for master image files at the LC. It is far and away the most popular file type present in LC's CTS system. It is heavily supported, open source, and maintains a good image quality. There is no reason at present to consider migration to other formats.
