The difference I have experienced using Vuescan does suggest that the scanner is accentuating the grain. However, I have had Delta 100 and 400 developed by labs and I have not had so much grain evident in the LS30 scans. As you say, it may be my developing time needs to be adjusted to reach the optimum. I shall experiment!
