Q1. Do you Have Source or COM Microfiche / Microfilm?
Look at the images on the Fiche/Film
|
|
Source images are taller than they arewide.
|
COM images are wider than they are tall.
|
* It is important to know the image orientation because some microfilm printers and scanners have screens oriented to capture either source or com. images Prism lenses can be added to many models in order to provide the image rotation neccessary for proper veiwing and printing.
Q2. What magnification is required to bring my microfilmed images back to original size?
* Your microfilmed images were reduces by a factor when originally filmed. Common reduction factors are 19X, 24X, 29X, 42X and 48X. In order for view, capture and print your images back to full size, the lens magnification factor needs to be determined.
Below is a Lens Chart that will help you determine the proper magnification lens you need to view your Microfiche.
Count how many images are going across one row of your fiche, then how many going down one column, use a fiche that is full of images with no empty spaces. See the chart below to find your required lens size.
If there is no match or you have Jacketed Microfiche, 16mm Roll Film, 35mm Roll Film or Aperture Cards, use our Lens Finder Template at the bottom of this page.
