• Figure 10, Scan and Output Settings
The Scan and Output settings (Resolution, Height and Width) are laid out to allow their
values to be easily compared, and to make the relationships between these fields more
apparent. The Magnification value from Scan to Output is no longer displayed, but is still
maintained by the software.
The operation of the six data entry boxes, Resolution, Height and Width, have been
updated so the Host Software accepts a value when you press your keyboard’s Enter or
Return key.
The Relationship Between Scan, Output and Magnification
The relationship between the Scan and Output settings and the underlying Magnification
remains the same:
Size
Output Width = Scan Width * Magnification
Output Height = Scan Height * Magnification
Resolution
Scan Resolution = Output Resolution * Magnification
The Size and Resolution are inversely proportional (i.e. as one gets larger the other gets
proportionally smaller). Simply stated, as an image is enlarged by a certain percentage
from the 35mm slide or negative to a specific output size, the overall size of the image
(stated in dots or pixels) remains the same. But, the resolution (measured in dots or pixels
per inch) is reduced by the same factor that the scan size was enlarged to the output size.
See Figure 11, Relationship Between Scan Settings and Output Settings. This figure
illustrates the affects of scanning the full area on a 35mm frame (0.96 x 1.44 inches) and
making a 4x6 inch print using the scanned image. This is a 417% enlargement from the
35mm frame to the 4x6 print. The 35mm frame was scanned at a resolution of 2000 dots
per inch (dpi), resulting in a 1920 x 2880 dot (or pixel) digital image. When the 1920 x
2880 digital image is printed on 4x6 inch paper, the resulting output resolution is 480 dpi,
