Just getting under the darkcloth with Paula and having her show you the magic is just part of it. you have to learn what to see. I used the Zone VI viewer for ever, but there isn't anything wrong with it it just doesn't give you what is really in the picture, Just the basic form. using the ground glass properly and seeing what M&P see is the whole thing. Technique in the darkroon and developing is a whole different thing you have to do.
