Manuscript, document and negative digitisation, Taryn Ellis

  1. 1. Digitisingyour collection Capturing bound manuscripts, documents and negatives
  2. 2. GettingStarted • Is the material uniform or varied? • Is the material fragile or have specific handling or technical needs? • Will we need training? Will we need to write a procedure to ensure consistent results? • What is the main purpose of digitisation and how will that determine techniques and technical standards?
  3. 3. This is where a caption goes. Maybe for two lines.
  4. 4. CopyStand • Two equidistant lights at 45 degrees • Camera parallel to and level with material • Camera with fixed macro lens • Colour reference card included • Trigger camera with computer, shutter-release cable, or set on timer.

  7. 7. Scanner • Easy to use • Can digitise small material in batches • Great for capturing content of flat/printed material • Files need little or no processing • Space and budget friendly Camera • Versatile • Fast (as taking a photo!) • Can capture a wide variety of material • Higher quality files that may require more processing • More accurate representation of material

  9. 9. • Camera on copystand • 100mm macro lens • Light box • Load up the scanner • Select settings • Go and have a cup of tea State Library of NSW. Photo by Russell Perkins State Library of NSW. Photo by Scott Wajon
