I developed some Agfa 25 in Xtol, and scanned the black and white negatives in a flatbed scanner at 3200 dpi. The 4 x 6'x are excellent, even with no special mount, and the negatives inside a transparent 4 x 5 film envelope. Even the 5 x 7's are not bad. But oddly, the unsharp mask seems to make the prints worse instead of better. The unsharp mask gives me golfball grain. Is this true grain or noise? Has anyone found a good way to scan black and white negatives, sharpen them, yet avoid the extreme appearance of grain?
