Final answer:
The statement is false; the main character in 'Blowup' is a British fashion photographer working in London, not an Italian cinematographer.
Step-by-step explanation:
The statement in question is false. In the film "Blowup", the main character is not an Italian motion picture cinematographer; rather, he is a British fashion photographer. The character, played by David Hemmings, works in swinging London of the 1960s and becomes inadvertently involved in a mystery after believing he has captured a murder on film.
Although the film does explore themes related to the visualization and perception akin to cinematography, the profession of the protagonist is distinctly in the realm of fashion photography.
