Thank you PE; that is both what I wanted to hear (I am not guilty of any process defect) and NOT what I wanted to hear (that this is considered 'normal'). I will have to live with this. The prints look fine but I know that if they were done digitally I would obtain just that little difference which, in comparison, can actually be noticeable. There is a tiny bit of 'dry down', like on some BW prints. - David Lyga.
