title: Simple and Inexpensive Identification of Film Negatives Used in Light Microscopy
abstract: : We describe here a simple and inexpensive solution for marking film negatives with identification numbers before film development. This technique avoids the purchase of expensive camera-magazines with data-backs, and it reduces the risk of misidentifying film negatives.
