This document provides guidance on digitizing collections of bound manuscripts, documents, and negatives. It discusses factors to consider such as the uniformity and fragility of materials, as well as the purpose of digitization. Setup and equipment for different digitization methods are described, including using a copy stand with macro lens or specialized book scanners. Technical standards for master and derivative file formats, resolution, bit depth, and color space are also outlined. Resources for further guidance on digitization standards and best practices are listed.
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?
5. 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.

Digitising a bound volume or document
8. 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
10. • Camera on copystand
• 100mm macro lens
• Light box
• Load up the scanner
• Select settings
• Go and have a cup of tea

Translation:
Unprocessed reference file
Large file that preserves all the digital information
More colour information
Refers to file size and describes pixels per inch (digital)
or dots per inch (print)
Represents a very wide range of colours
Processed file for viewing and sharing
Compressed file, less space on hard drive
Less colour information, less space on hard drive
File size in pixels (ppi / dpi irrelevant)
Smaller colour range- standard for internet
