Technical specifications for graphic material
- Creighton Barrett
Owned by Creighton Barrett
Introduction
- This page provides technical specifications for the digitization of photographic prints, posters, illustrations, maps, technical drawings, slides, and negatives
- Choose 24-bit colour if the scanner cannot create 48-bit colour image files
- Choose 8-bit grayscale if the scanner cannot create 16-bit grayscale files
- Sepia prints should be scanned with technical specifications for colour prints but saturation should be increased to +100
- Brightness, contrast, and saturation specifications are provided as a “starting point.” Technical specifications should always be tested and adjusted if necessary before scanning a new batch of material
