In the 1954 film Rear Window, what is L. B. Jefferies’s profession?

In Alfred Hitchcock’s 1954 film Rear Window, L. B. Jefferies is a photographer.

James Stewart plays Jefferies, a professional photographer confined to his Greenwich Village apartment after breaking his leg. From his rear window, he watches the lives of neighbours and becomes convinced that one of them has committed murder.

The film turns professional photography into part of its mystery structure: Jefferies is accustomed to framing, enlarging and interpreting images, but his viewpoint is also limited and potentially unreliable. Rear Window was adapted from Cornell Woolrich’s 1942 short story “It Had to Be Murder.” The character is sometimes described generally as a photojournalist, but the film specifically presents him as a photographer.
