Michael,
I don't see anything condescending in my comments. I have followed Mann's work for a number of years. I very much enjoy her landscapes, her familial portraits, and most of "What Remains." However, I have seen the large wetplate prints "up close and personal." I have listened to her recorded artist statements on them. I do not believe that they are her strongest work.
As for understanding work, I find that comment condescending. Pictoralism is art, modernism is art, Ryman is art. And, yes so is Sally Mann. I have studied the battlefields that she shot for more than 25 years. Walked them foot by foot. Photographed them, thought about them, and dealt with the conflicting feelings of beauty and horror. If it pushes the medium to create 5' soft focus, dark enlargements of wetplates, some coated in beeswax, I think that is great. Maybe we are seeing a cyclic return of pictoralism. I leave that for others to determine.
I am impressed with Rob Gibson's day to day work. I am impressed with most of Sally Mann's work. But as for the "unsupported by either a critical eye or an educated assumption," you can mean nothing but a confrontational and condescending attack. And you are quite welcome to that opinion.
I urge everyone to go out and see Mann's work when they get a chance. I urge them to watch the PBS special on her. I urge them to read her books and listen to her artist statement. If they agree that the prints in question are wonderful examples of the medium, great. That does not make the opposing view uninformed or uncritical however.
Mike
