Photographs by Johnson have been included in five exhibitions and books produced by the Smithsonian Institution.  He has contributed photos to 45 books, four films, a music video, and over 65 magazines.  In 2006, Johnson published his first book, Soul Sanctuary: Images of the African American Worship Experience (foreword by Gordon Parks).  It was on the Essence bestseller list for three weeks.  Fifty of those photographs are now in the permanent collection of the Smithsonian National Museum of African American History and Culture.
