2.
Click on the Video tab to activate the Micro-Image Capture unit and display a video
image of your microfilm.
3.
The default mode is color, but the Grey Scale, Black Line and Color Inverse modes are
more suitable for viewing and capturing microfilm images on most media. Now click the
Grey Scale option to remove color from the image. * You may need to slide the
“saturation” slider up and down to fully remove the color *
4.
The image will probably be out of focus initially, so raise or lower the MIC head unit
using the large black knob on the side of the unit until you see some sort of image, even if
out of focus. We will first concentrate on getting image settings correct, and then focus.
5.
Adjust the image quality by un-selecting the auto exposure box and manually adjust the
exposure to provide a viewable base line exposure.
6.
Adjust the brightness and contrast in order to achieve the most legible image in the grey
scale mode. Dark portions of your image should be as black as possible while light
portions should be white, not gray.
7.
Adjust Gamma to remove excess gray in the background of the image in order to achieve
a best possible contrast.
8.
If you are viewing negative film, you may now try the”Inverse mode” in order to see the
image with a more natural white background and grey/black text (aka positive mode)
9.
When switching from “Grayscale” to “Inverse mode”, you may need to re-adjust some of
the settings in order to achieve the best view and scan result in that mode.
10.
If you have high quality film with very good film density and contrast, the “Black Line”
mode will provide an excellent negative image to view and print with, but you will have
to program Snagit to invert the output color by choosing “Color Substitution” , then
“Invert Colors” so that your output print and scan will be positive. More on this in the
Snagit adjustment section.
11.
Using the scroll wheel on your mouse will enlarge and reduce the onscreen image of your
microfilm while in the user interface mode only.
