I just completed a test with Dixactol and Delta 400. I used the two- bath method. The negatives look great but I was expecting more stain that I got. The tests indicate that 200 ISO is where I need to be when I shoot the film normally. I am curious as to the amount of stain that you got and the benefits of one-bath vs two-bath.(posted 8508 days ago)I wish I could advise you on the formula for B solution. Good luck.
