A recent issue of Photo District News included an essay on noted photographer Harry Callahan's influence on his colleague, photographer Emmet Gowin.
Apparently, Gowin shot some street photographs in the style of Callahan's earlier work. When Callahan later saw them, he remarked: "I wish I could've done all of those. There was a time I could have and now I can never go back to where I was."
"This is a very important thing for young artists to know,"Gowin said, "to be in the time and place which is appropriate. That which is appropriate – which is to say, that which is your property. Something is proper to me, it's right for me, it's near my core, it belongs to my emotional orientation.
