[1] His four main books each contain portraits of people Renaldi met in public, and some landscapes, made over numerous years with an 8×10 large format view camera.
Those books are: Figure and Ground (2006)—various people throughout the USA;[2] Fall River Boys (2009)—young men (and some women) growing up in the post-industrial city of Fall River, Massachusetts; Touching Strangers (2014)—strangers posed by Renaldi physically touching in some way, made all over the USA;[3][4][5][6][7] and Manhattan Sunday (2016)—LGBT people photographed between midnight and 10 am on Sundays[1] mainly on the streets of Manhattan having left nightclubs.
[8][9][10] Touching Strangers had a solo exhibition at Aperture Foundation, and Manhattan Sunday,[11] for which Renaldi received a Guggenheim Fellowship in 2015,[1][10] had a solo show at George Eastman Museum.
Touching Strangers was made over seven years, beginning in 2007, and inspired by an earlier series of Renaldi's, Bus Travelers, "that looked at the intimate spaces strangers often share.
Renaldi established Charles Lane Press in 2008 to publish new projects by contemporary photographers.
