The Min*lta scan utility I use provides "the color depth can be selected
from 8 bit, 16 bit, or 16 bit linear". I use the 16 bit option. I saw a
number of newsgroup posts about compressing the image file but didn't
try to follow them.
I've read claims that manipulating an 8 bit image can result in problems
but that 8 bit is just as good for printing.
I've got a lot I need to learn about it.
