Software Reference for Scanners
The Smooth Scaling checkbox sets a pixel averaging interpolator to produce
smoother pixel transitions in low resolution (Pitch 5 to 50) scans.

The Highest Quality checkbox will cause the scanner to take the scan in a
special slow-speed mode to improve the registration accuracy in low resolution
scans (from pitch 5 to pitch 50). In almost all cases, the difference from the
normally high-quality fast scans will be negligible.

Scanning Speed
There are several ways to optimize scanner performance.
You should allow Adobe Photoshop to have as much memory as possible. In
order to do this, you should find the application in it's home folder, select it with
the mouse, then select the
Get Info menu item in the File menu. A dialog will
appear with two boxes in the bottom right corner: Suggested Size , and Current
Size (in System 7). The Current Size box will be editable. Type in a number
greater than that in Suggested Size , and at least 2 MB less than your maximum
system memory size. When Adobe Photoshop is launched after this, it will use the
maximum possible memory up to the value that you typed in. If you consistently
get a dialog that tells you that the application will be opened in a smaller partition,
you should go back into the "Get Info" dialog, and reduce the memory
requirements.
System 7 users should have 32-bit addressing on and virtual memory off in
the memory control panel for best performance with greater than 8MB of RAM
installed. Minimum requirements for higher performance at high resolution are
32MB installed RAM, addressable under System 7.0.
Scan in Portrait mode and place the slide in the holder in the appropriate
position to get the right preview orientation. This delivers data to Adobe
Photoshop in a more efficient manner than
Landscape mode. You might select
the crop in Landscape mode, then switch it to Portrait mode just before the scan
is to be made.
In some cases, Flips may slow the scan by a small amount. Experiment to
see which delivers the best results for you.
Try to use an integer pitch setting. These will always be more efficient than
non-integer pitches. Experiment with selecting crops and specifying integer
pitches for them.
