Delta 400 in perceptol? Simply beutiful BUT, and it is a big BUT, if you're shooting 35mm, I found to my eye that the edges were 'soft', giving the appearance of a slight lack of sharpness (ie. the opposite effect of what Rodinal does).(posted 8112 days ago)I haven't used this combination in MF so I don't know if it is as apparent in prints made from MF.
