The importance of performing extensive calculations on microdensitometer data makes entry of the data into a computer mandatory for many types of investigative situations. The previously available facilities in the Photographic Science department have supported only manual data entry techniques. Such techniques are slow and prone to error, greatly limiting use usefulness of the Ansco Model 4 microdensitometer available for student use. This thesis has involved the designated implementation of a low cost digitizatio technique that allows convient gathering, storage, and machine read input of data into the RIT timesharing computer facilities. A conservative increase of two orders of magnitude has been noted with the system compared with manual data entry techniques
