This is so the scanner's CCD and software know how to interpolate my film (that's my understanding at least, if I'm wrong, please correct me accordingly). If you try to scan C-41 B&W as 8 or 16 bit Grayscale, the image usually does not produce what you would expect from a B&W image. If memory serves me correctly, you'd end up with this horrid looking image that's no where close to the actual image on the neg. Contact me off list if you want or need a sample of both.

Why scan in color mode when the image is entirely grayscale in nature? What is gained by treating the image as a color image since it's black and white anyway? This is NOT a troll - I just don't understand.
