Mr. Conrad was on assignment to do a portrait of Joel Meyerowitz, the influential color photographer whose half-century career takes up a massive two-volume book, and an exhibition. Elaisha Stokes, a freelance videographer for The New York Times, shadowed Mr. Conrad taking Mr. Meyerowitz’s portrait in his studio on the Upper West Side to accompany an article by Randy Kennedy.

Lens also recently published a post by Mr. Meyerowitz on his approach to color and black-and-white photography.
