Mitch Epstein is a photographer that first came to my attention via his series Family Business. Upon further review I realize my admiration goes back further, not realizing some past favorite photos were his as well.
Family Business remains at the top of my list, perhaps because it seems most personal. It chronicles his father's life after the fall of his once thriving career as owner of one of the largest furniture and appliance store's New England. Some photos featured here are from this series. I encourage you to check his site for more.
