Hey, ever since i've developed, i end up with enormous amounts of watermarks on my negatives and i end up having to use the special remover with intense scrubbing. Is there anyway to prevent the watermarks from forming. I use Ilford 400 pro, develop with metal reels and Kodak dev. stuff. When it's finished, i hang it with clothes pins from string in the dark room with a weight on the bottom. I do wet my finger and slide it down the negatives to get rid of most of the water, but it still is there. Any ideas?
