D. Set Output Size (Width/Height, Magnify, Resolution)
This section provides a brief explanation of several of the items in the
Output Size area of the Settings tab. For a full explanation refer to the
Output Size and Input Values
section of this manual.
You control what portion of the frame will be scanned and at what resolu-
tion. One way you control the part of the frame to be scanned is by drag-
ging a crop box as explained above; this results in changing the Scan Area
(Width and Height) shown on the screen to the right of the image. You
control the scanning resolution (also to the right of the image, as the Input
Res) indirectly as explained below.
You control the dimensions of the resulting image by changing the Width
and Height (Output Size). Finally, you control the output resolution by
changing the Resolution (Output Size).
The translation from Scan Area and Input Res to the dimensions and reso-
lution of the scanned image is controlled by the same magnification (Input
Size Magnify). But magnification affects the translation of dimension and
resolution differently. The more you increase the dimension of the output
image, the smaller the output resolution will be because the scanned image
has to be spread over a larger area than on the film. The more you decrease
the dimension of the output image, the higher the output resolution will be
because the scanned image has to be compressed into a smaller area than
on the film.
Because of the interrelationships between width, height, resolution and
magnification of input and output, whenever you change one of these
values, the software will automatically change one or more of the other
values to compensate. Also, the Output Size Lock box, when on, freezes the
output dimensions, and therefore the Scan Area is forced to maintain the
aspect ratio defined by the Output Size Width and Height.
