Yesterday I visited the Gagosian gallery in Beverly Hills to see the Sally Mann show. There are about a dozen 40x50 inch prints from wet plate collodion negs. The photos are all close ups of her childrens faces. Interesting effects due to the long exposure times & fragile nature of the emulsion. The look of the prints is impressive but I would like to see them as contact prints rather than enlargements as I think this would emphasize more the surface characteristics of the original plates. I suppose they need to be 40x50 when you are asking $40k per print.
