Alot of photographers, don't know how to tell the story, and that is not a put down, but every product needs a story to have value, or we become the Walmart of the photography world and value goes down, I have often heard from many friends who take pictures for a living, the taking part is 10% and the marketing part is 90%..I agree with Robert to a certain extent, many images can tell their own story, but for the mass majority in a society that is bombarded by images in virutally ever aspect of their daily life, they need to see why, when, what and how and in the case of more expenisive images, the buyers needs to feel they have personal relationship with the artist..and in the case of gallery sales, the person representing you, must be able to build that personal relationship, or they have no business selling art.

Just what has worked for me and my .02
