PhaseOne captureback overhead scanning station:


Introduction:

Overview

The PhaseOne Overhead scanning station is comprised of a medium format camera with a hi-res digital back. The combination of the speed of a film photography camera with a digital image capture sensor make the PhaseOne station the most versatile, fast, and powerful scanner in our digital program.


Usage

The PhaseOne captureback can be used for large format materials upwards of 40 to 50 inches, all the way down to very small materials like coins or stamps. Due to this scanners very fast image capture and optimization cycle, our group relies on this scanner to take on all different types on materials. some materials that are scanned on this scanner are; newspapers, manuscripts, maps, photos, large format negatives (on a lightbox). Large collections with many objects that need scanning are completed much more rapidly with the capture back as apposed to a flatbed scanner.
