History of Microfilm:

Technically, this is the reason, "The duplicating technician can change the lamp and speed settings of a duplicating machine to increase or decrease exposure from the master negative onto the print master. The type of microfilm can play an important role in improving the print master densities by choosing high-contrast or low-contrast microfilm stock. Where you take the density readings throughout the reel can have a great effect on the "average". The average decides the duplicator settings and that can make all the difference in good print masters for scanning. Click here to see an example. It has been said that a technician can find any density reading on any piece of film if they’re willing to look for it. It’s true."

Intellectual the reason for the start of microfilm scanning was totally different. To allow the scanning technician to know that the microfilm scanner has captured everything present on the microfilm reel. To allow the metadata technician to confirm that missing issues, pages, duplicate issues or pages, and other anomalies are consistent with what is on the microfilm. This is where every thing started.
