If we accept the interpertation that a legacy is something that is handed down to succeeding generations then I find it difficult to make a determination who has had the greater impact. Certainly the hometown photographers have over time facilitated others as they have engaged in the leaving of a legacy. Have they themselves actually left something behind. Yes, I imagine that you can say they have. But what is it and what has it amounted to?
Accepting the interpertation of legacy as stated above, I also must allow for the fact that Curtis, Weston(s), Adams, Sieglitz, Strand, among a vast number of others have left a legacy that is rich and varied on the professional practice of photography.
As I see it legacies have been left by both groups. The legacies that have been left are different and both are of value.
I wonder how proficient any of us would be if we had only the hometown photographer from which to draw our knowledge, appreciation, and experience of photography as a means of expression.
