What is Microfilm ?

Originally, microfilm was created in the 1800s; however, it was not put to significant use until the end of the 1920. When it was developed, banker George McCarthy held the right for the machine that is capable of producing microfilm. It was mainly used for making permanent film copies of bank documents with the use of a special camera. The records produced can resist deterioration and help provide storage space. In 1928, Eastman Kodak bought the rights to microfilm machine, which helped shoot it into the market.

New York Times started creating copies of their newspaper in 1930s to save for later use. However, the paper Times used to make these copies deteriorates fast. In conclusion, Times decided to switch to microfilms and became successful with the process. Then, Harvard University started with their microfilm project that still being practiced today.

A special camera capable of taking footage in a small scale is used to create a microfilm. The specific cameras’ technology can reduce a document up to 99% from its original size. Then, the image is printed in a black and white film comparable to the negative of a photograph.

There are two kinds of films used to create a microfilm, vesicular film and silver halide film. Vesicular film utilizes microscopic bubbles to produce image in a polyester strip. Silver halide film on the other hand, is much like a regular film, which the image is transferred to the film using silver emulsion to the polyester strip. Microfilms can be viewed using a machine similar to a big microscope. The machine enlarges the image that allows the contents to be read. If stored in a special envelops or in a temperature –controlled room, a microfilm can last up to 900 years.

    One thing I’d like to say is that often before obtaining more laptop or computer memory, look into the machine within which it is installed. If your machine is actually running Windows XP, for instance, the particular memory ceiling is 3.25GB. The installation of more than this would purely constitute any waste. Be sure that one’s motherboard can handle your upgrade amount, as well. Good blog post.
