REGARDING THE SETTING ITEMS OF THE PREFERENCES WINDOW
Auto Expose for Slides
This option allows you to select whether to perform the auto exposure during the prescan or the
final scan when using color slides. As the color slide users often adjust the exposure and color
when taking a photograph, the Auto Expose function when performing the prescan or final scan
is turned off in the default setting (The checkmark is not on the checkbox). However, when
scanning the slide which is short of exposure or when using the AE Lock or AE Area lock
function (p.38, 39), click on the checkbox of "Auto Expose for Slide" so that the Auto Expose
function is turned on.
Auto Focus at Scan
This option allows you to select whether to use the Autofocus function when performing the
prescan or the final scan.
To obtain higher scanning speed, the Autofocus function is turned off in the default setting (The
checkmark is not on the checkbox). However, if you intend to use the Autofocus function when
scanning, click on the checkbox of "Auto Focus at Scan".
When using the Digital ROC or Digital GEM function (p.69 to 73), it is recommended to turn on
the Autofocus function by clicking on the checkbox of "Auto Focus at Scan".
Close the Driver Software After Scanning
This option allows you to select whether to close the driver software after scanning when using
Twain driver or Plug-in Software and image editing application.
The driver software is specified not to be closed after scanning in the default setting (The
checkmark is not on the checkbox). This setting is convenient when scanning the multiple
images continuously and loading them into the image editing application such as Adobe
Photoshop. On the contrary, when retouching the image with the image editing application
every after scanning a image, click on the checkbox to display the checkmark.
Color depth
This option allows you to specify the format when outputting the scanned data to a file or an
application software. Select one from the following items of the list box.
The default setting is 8 bit.
8 bit
Outputs the image of 24 bit in each R, G or B of 8 bit
16 bit
Outputs the image of 48 bit in each R, G or B of 16 bit
16 bit linear Outputs the image of 48 bit in each R, G or B of 16 bit that any corrections
such as a gamma correction are not made. Therefore, when scanning a negative film, it is
output as a negative image.
* Only TIFF can be selected when using the utility software and selecting 16 bit or 16 bit linear
as a color depth.
* When selecting 16 bit, the image size display in the Scan Settings window is represented in
the 16 bit size (8 bit x 2).
* Depending on the application software, 16 bit image file cannot be handled.
