Upon arriving, Cubitt began to document the area's devastation. He set up a photography studio in order to interview and photograph Katrina's survivors and volunteers in Pearlington's former school gymnasium, which was serving as a distribution point for aid in the town. Cubitt published their stories and images on a blog he created, titled "Operation Eden." For a time, the blog became a central hub for volunteers and people seeking to send relief, and citizens who were curious about what the mainstream media wasn't covering. The blog has been described as "a powerful piece of citizen journalism." It was featured on MSNBC, LIFE Magazine, and Rolling Stone. Cubitt returned to the area subsequently to photograph survivors in Mississippi and New Orleans. His Katrina portraits were used by ad agency Grey Worldwide, in conjunction with SAMHSA and the Ad Council, to create a series of PSAs urging Katrina survivors to reach out for help. Cubitt’s celebrity portrait subjects include David Byrne , Peter Murphy, Xeni Jardin, Levon Helm, Shaun Ross, Big Freedia, Justine Joli, and Molly Crabapple. Cubitt is credited for initially discovering underground South African rap-rave group Die Antwoord, and subsequently shot their portrait and album cover for the band's debut, $O$. In 2008–2009, Cubitt created a video series of Long Portraits, in which subjects were filmed sitting still for five minutes or more. The Long Portrait format became popular on Vimeo, inspiring many other photographers to create their own versions. In 2012, Cubitt created a video series entitled "Hysterical Literature". Shot clinically in black and white, each film shows a fully dressed woman reading a passage from a book of her choice while brought to orgasm by a vibrator controlled by an unseen assistant under the table. The first installment in the video series featured adult performer Stoya reading "Necrophilia Variations" by Supervert, and has received over twenty-three million views on YouTube as of May 2018. Subsequent videos feature "friends and industry comrades" like Margaret Cho, Toni Bentley and others  reading passages from books including Bret Easton Ellis' "American Psycho" and Walt Whitman's "Leaves of Grass". In 2016, Cubitt became a vocal supporter of senator Bernie Sanders' presidential campaign. Cubitt photographed war veterans and interviewed them about what Sanders' candidacy means to them. The images were used by the official Bernie Sanders campaign. Group Shows
