Emil first I wasn't refering to Weston whom I believe to be one of the trully great photographers (still prefer Brett though) but to an american landscape deity who imho is the most overated photographer in the history of the medium but that's all it is a personal opinion. Ms. Mann is at home in the gallery scene which requires a as you call it schtick otherwise you are hard to sell. Mrs Mann early work is technically perfect, so are the enlargments of her wetplate work. So she knows her technique quiet well. I've seen a Mann hanging next to a St. Ansel and guess what I vastly prefered her work but then again I also like work produced with the Holga, Diana, and other Toy cameras.
To the OP
I had the same results from an overexposed roll of Konica centuria 100 (miss that film most beautiful pastel tones ) ric_kb could be right though
