Timothy Greenfield-Sanders doesn't mean to be a name-dropper - he just can't help it. The portrait photographer sees so many famous people each week that his casual conversation is peppered with reminiscences about movie stars, politicians and art world luminaries. "I know everyone," he admits. "I could get up in the morning and Jasper Johns would be at the breakfast table, or John Malkovich would be here for lunch, or Karen Finley would have dinner here."
