Using The Macintosh Scanner Plugin
The Highest Quality checkbox will significantly slow scans. Make sure that
you absolutely need the advantages that it provides for low resolution scans.
Finally, different images will have varying scan times dependent upon their
density. When the scanner makes an autoexposure, it decides upon some baseline
parameters to optimize the image to be scanned. One of these parameters is
exposure time for each color. Higher densities require longer scan times.

Grayscale/Color Preview

Fig. 38 Previewing in Color
Pressing the Preview button will cause a preview scan to be taken. To
preview your image in color, check the In Color checkbox. Previewing in
grayscale allows fast black and white previews of color scans when a quick scan
and crop is required for expediency.

Interface Buttons

Fig. 39 Interface Button
This toggling pair specifies SCSI or GPIB interface. While opening the
plugin, the software will search the GPIB and then the SCSI bus for any scanners.
When found, the device found will have its ID displayed in the upper right-hand
corner. If no device is found, and one is known to be connected, then the toolkit
button provides a means to search the bus again for a particular address.

Digital and Analog Controls

Fig. 40 Digital Control
In order to save dialog space, and to keep the user interface as uncomplicated
as possible, we have assigned dual roles to the five edit items in the lower left
hand corner of the Main Scanning Dialog. These items double as brightness,
contrast, and tint level (digital), and as exposure time, black level, and color
balance (analog). The principal difference between the two types of adjustments is
that analog adjustments work on the actual CCD voltage levels and exposure
times; while the digital adjustments work on the data after it has been collected
from the CCD and digitized within the scanner. The advantages of using the
