Wow, I never thought of it that way...that Michael and John are the leading practitioners of the Adams and Weston schools. That's very cool.
As for the doing enlargements and contacts spearately, it is simply a matter of logistics: since I have no darkroom at the moment, I do azo printing in the kitchen at night after the family goes to bed, and I do enlargements at a rental darkroom about fifteen minutes away. So I tend to do Azo printing whenever I am awake enough to stay up, and tend to do enlargements in batches on an otherwise empty Saturday. And it just so happens that I had not displayed both at the same time in the same light until recently.
