Overview:
Modern digital imaging techniques continue to advance, providing archivists, historians and researchers with a broad range of ways to digitize, and reproduce a wide variety of materials. When we think of scanning, we usually think of photographs and text. However, other items one would not normally consider scanning, are well served by this process. Likewise within the realm of standard scanning, there are certain techniques and processes that help enhance and manipulate traditional scanned items. Know which technique to use as well as what post-scanning processing techniques greatly enhance the final scan.
Subject Matter:
- Photographs (color & monochrome)
- Transparencies (slides & negatives)
- Printed images (half-tones)
- Oversized items
- Line Art
- Text & Optical Character Recognition (OCR)
- Non-flat Objects
Techniques & Process:
- Historical background (Photo engraving, copy cameras, drum vs. flatbed scanners)
- How scanning worksResolution: dpi/ppi vs. actual size
- De-Screening of printed images (newspaper & magazines – screen frequency as dpi)
- Scan settings: (gamma, contrast and levels)
- Post-scanning editing
- Using layersScanning objects, (pocket watches, campaign buttons, etc.)
- Scanning larger items (Scanning vs. Digital photographs)
- “Stitching” multiple scans
- File formats (lossy vs. non-lossy)
- File naming & organization
- Archiving digital media (Optical vs. Magnetic storage)
- Using scanned images: (print material vs. online)
