I agree, it seemed much truer than the Rick Burns film for PBS. The title of the 1981 film is Ansel Adams: Photographer, produced by Andrea Gray and John Huszar. Andrea was Ansel's assistant for six years while Rick Burns had to rely on the likes of the late John Szarkowski and others. There was also a fairly brief, but interesting, TV documentary in 1957. It featured much of the extensive equipment Ansel toted around in an eight passenger Cadallic limousine with the famous platform on its top.
