Hardware Options Nikon

Every scanner offers some hardware features, which can be accessed via this panel. Of course this panel may be different with different scanners. But this one is which we use for all Nikon scanners. Depending on the selected color depth some of the features may be disabled.


Brightness
Brightness acts like a brightness adjustment.
 
Contrast
Adjusts the contrast of scanned images.
 
Shift
Shifts the color components red green and blue.
 
Exposure Time
Larger values of Exposure Time result in a higher resolution and brighter images. The Exposure Time value equals the integration time per line of each color component of the scanner. Be aware that higher Exposure Time values lead to a non linear increase of scan time.
 
Focus
Sets the focus of the scanner.
Guess
Performs an auto focus run by the scanner.
Automatic
Auto focus is performed before each scan.
Object Type
You may choose between Negative and Positive slides. If you choose Negative the image data will be inverted.
 
Gamma
You may choose between two different Gamma curves.
 
do prescan
Enables or disables the automatic prescan before any actual scanning. Recalibrates the exposure time base for the current scan if enabled. One prescan should be done on any image to be scanned.

Note: These features enhance or manipulate image data before they are transferred into the computer system. Therefore there is no way to revert this conversions, than to repeat the scan with different values. This may be faster than a software operation on images.
