Color-depth list box: this option specifies the color depth of the scanned image between 8 bit, 16 bit, and 16-bit linear for each RGB channel. Because 16-bit linear color depth does not make any gamma corrections, the scan of a negative will produce a negative image. 16-bit and 16-bit linear images can only be saved in the TIFF file format. Some image-processing application cannot open 16-bit image files.
Multi-sample list box: multi-sample scans reduce random noise in the image by analyzing the data of each sample scan; 2, 4, 8, and 16 samples can be made. The more samples taken, the less random noise in the image and the longer the scanning time.
Retouching level: to adjust the degree of Auto Dust Brush processing. See page 38.
