Before undertaking a microfilming project, a local government official must learn some microfilming basics. This does not mean the local official needs to become a technical expert! Knowledge of the fundamentals of microfilming allows the local official to work efficiently with vendors and will ensure a quality product. The following publication briefly introduces some microfilming concepts, terms, and equipment. A glossary of microfilm terms can be found at the end of this publication.
This publication is one of three microfilm publications in the Local Government Records Technical Information Series. Technical standards are discussed in Producing High Quality Microfilm (Technical Information Series #9), and project management is discussed in Managing Micrographics Projects (Technical Information Series #10)[Replaced by Publication #77].
Microfilm is fine grain, high-resolution photographic film capable of recording images. It was developed at the turn of the century and was refined and used heavily during World War II. This mature document technology continues to evolve and currently is seeing a resurgence as a component of many hybrid imaging systems.
The process of actually putting the image on film is relatively easy. A camera takes a picture of a document. The camera negative is developed and duplicated. The film is viewed on a reader that magnifies the image. However, to produce quality microfilm that is readable, properly identified, easily accessible, and meets the technical standards is not a simple process. Local government officials must be prepared to spend time during the entire process, from selection and preparation of the records to be filmed, through the final inspection and distribution of the microfilm.
