More than 40 years of pop-music history are covered in Barnaby Clay’s documentary, “Shot!,” about the life and career of British photographer Mick Rock.

Clay’s very engaging subject jokes he was probably destined to shoot pictures of music stars, ranging from David Bowie to contemporary artists such as Father John Misty, because his last name is the one he was born with.

The 25 people who gathered for the screening at the Palace Theatre in Danbury were very enthusiastic about the movie, with only a few reservations about Clay’s dramatized scenes of a heart attack that almost killed Rock (like many of the stars he shot in the 1970s and 1980s, the photographer over-indulged in booze and cocaine).

Rock is best known for the work he did in the 1970s with Bowie and other “glam” rockers, but he still lands many gigs shooting celebrities for major magazines. We also see him signing copies of one of the coffee table books that preserves his work.; Twitter: @joesview
