Kenneth, sorry for delay replying to this, but I didn't notice you had started a new thread. There is another thread above where most of the traffic on this article has been occuring - anyhow no harm - just so you'll know I had no intention of ignoring you. I would say the average digital file that doesn't need much tinkering takes about 10% to 15% of the time that a scanning process would need to accomplish the same thing. The productivity differential is truly remarkable.
I don't know the Epson scanner at all - don't own one and never seen it in operation, so unfortunately I can't answer that question. Also, I've never done batch scanning. I work one image at a time. Maybe that's because I'm not in this to earn a living!
