Numeric Examples

Let's look at several numeric examples of the relationships between these
items. You'll note below that the software will change some parameters in
the formulas, but not others. A table following the examples provides the
specifics of how a change in one parameter will change other parameters.
1. Suppose that you choose a Magnify value of 200%, and an output Reso-
lution of 1500 dpi. In this case the scanning software uses formula
number 1 above to compute the scan resolution at 3000 dpi, that is
1500 dpi x 200%.
If you change the output Resolution to 1000 dpi, the scan Resolution
changes to 2000 dpi and the magnification stays at 200%.
However, suppose that you change the output Resolution to 2000 dpi.
This means that the scan resolution would have to be 4000 dpi; how-
ever, that exceeds the 3600 dpi capability of the scanner. In this case
you will see a message and then the software would reduce the output
Resolution to 1800 dpi, causing the scan Resolution to go 3600 dpi.
2. Suppose that you enter an output Height of 30 mm and a Magnify value
of 200%. Here the software uses the formula to compute an input
height of 15mm; since this is smaller than the frame size, a crop box
will appear automatically over the image. Move the crop box as desired.
If you change the output Height to 20 mm, the software changes the
input height to 10mm, and changes the size of the crop box.
However, suppose that you change the output Height to 50mm. This
means that the input height should be 25 mm; however, that exceeds
the height of 35 mm film (24 mm assuming the image has not been
rotated). In this case you will see a message and then the software
would reduce the output Height to 44 and set the input height to 22.
3. Suppose you set the Magnify value to 200%, the output resolution is
900 dpi, the output height to 30 mm, and the output Width is 50mm.
The scan Resolution will be computed to 1800 dpi, the input height will
be 15mm, and the input Width will be 25 mm.
Assume the output Width and Height are unlocked. If you double the
magnification to 400%, the output data are changed to resolve the
formulas. Here the output Resolution is halved to 450 dpi, the output
Height is doubled to 60mm, and the output Width is doubled to
100 mm.
