Abstract:

A flatbed scanner may not be an answer to all the libraries’ and archives’ digitization needs. When a bound book is scanned by using a flatbed scanner, page curl is inevitable. Archives often hold brittle items and artifacts that may be harmed if this type of equipment is employed. Cradle scanners with cameras overhead are bulky and expensive. Here is where DIY digitization systems utilizing DSLR cameras come into the picture. The paper suggests a reasoned approach to the choice of a technical platform for creating and manipulating digital images. Three professional DSLR camera systems, Canon vs. Sony vs. Nikon, are discussed in terms of their vital features. The size and type of the sensor; image quality; ergonomics; changeable lenses; image processing and post-processing capabilities; signal to noise ratio and noise reduction; image stabilization and auto focus; battery life; LCD display; low-light reliability; and other features are reviewed. Comparative analysis of the cameras’ performance in relatively difficult conditions (poor lighting or glare, documents capturing) is provided. Additional accessories are juxtaposed. Proprietary software packages are compared to the cross-platform compatible Adobe Photoshop. Preliminary expenses for the minimal equipment sets are provided on the example of the Medgar Evers College library. Recommendations for choosing a platform for a limited budget institution are given.
