This question grows from another thread currently running, but sparked a question in my mind...
I remember accounts of photographers in the 1920's and 30's journeying to New York to have Alfred Stieglitz review their work; most had their hopes dashed, a few received positive reviews, a select very few were even offered shows at 291 or An American Place.
Later, photographers took their work to Ansel Adams, who was usually more gracious and encouraging. He was the "Grand Old Man" of American straight photography, and his opinion held much weight. Minor White held a similar position for those who sought some level of transendence in their work, and many went to have him review their work or to study under him
If today you had produced a defined portfolio which you felt achieved your vision and you wanted to show it to one person, not for marketing purposes or publication, but to ask, simply, "is this of value," who would you take it to?
