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 | |
|
|
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.
