[citation needed] His father, Earle David Tunick, founded Resort Photo Service, a photography business that photographed private events as well as those of famous politicians, singers, actors, and athletes.

[citation needed] Tunick studied at the New York Military Academy, and later earned a degree in Fine Arts from Emerson College in 1988.

In Sydney, Australia, 5,200 volunteer Australians posed nude in 2010, and at the Dead Sea in Israel in 2011, around 1,200 participants paid to join the installation.

[citation needed] The many volunteers who participate come from diverse societal groups, and by shedding their clothes, they become a single homogeneous entity—an integrated structure stripped of individual identity, social, cultural, economic, or political distinctions.

[citation needed] To mark International Women's Day on March 8, 2021, the 24th session of the Stay Apart Together project saw Tunick and Vanden Broeck collaborate with Mexican-American visual artist Daniela Edburg to depict 75 Latin American women in 11 poses, incorporating the colors purple and green (symbols of the Latin American feminist movement) and hot pink, selected by Edburg for its liveliness.

A "regimented" quality has been observed in the arrangement of figures in some of Tunick's work, but this may be offset by the social transgression that accrues to public nakedness.

[9] Later, in September 2001, Tunick photographed 400 nude volunteers in Greenwich, London, each side of Cutty Sark, and then in a nearby street.

[17] On March 19, 2006, Tunick photographed 1,500 nudes in Caracas, having people standing up, lying down, and on their knees beside the main Simón Bolívar statue.

On June 3, 2007, he photographed installations with 2000 participants in Amsterdam: 2000 people in a car park; 250 men at a nearby gas station; and 250 women on bicycles on the Lijnbaansgracht — Lauriergracht.

A small group of participants was photographed on a canal, Leliegracht, requiring a special bridge construction to create the illusion that the people were floating over the water.

[23] The environment-oriented installation was reported in several languages and media outlets around the world, Swiss politicians were playfully encouraged to demonstrate their green credentials by participating in Tunick's installation, and Euro RSCG Zurich, Switzerland received the AME Grand Trophy for Public Service and Not-For-Profit, for their campaign for Tunick and Greenpeace Switzerland, "Naked Testimony to Global Warming".

[25] Tunick announced plans to take photographs in Ernst Happel Stadium in Vienna with 2,008 naked football fans in the run-up to the Euro 2008 tournament.

Another photoshoot was organised for four days later (Saturday June 21) in Dublin, on the South Wall near the Poolbeg Lighthouse, with over 2500 nude people taking part.

On October 3, 2009, Tunick performed another installation in collaboration with Greenpeace, this time to draw attention to the effect climate change is having on French wine production.

The press were allowed a photoshoot at Peel Park, Salford on May 1, but the other locations such as Castlefields, Dantzic Street and Ringway remained unreported.

[32] On August 8, 2010, around 700 revellers at the Big Chill Festival, at Eastnor Castle Deer Park in Herefordshire UK, shed their clothes and covered themselves in five shades of body paint for an installation that paid homage to the art of Yves Klein, Mark Rothko and Ellsworth Kelly, and made reference to the BP oil spillage in the Gulf of Mexico.

On the following morning Tunick set out to re-enact Eugène Delacroix's "Liberty Leading the People", with the help of 250 women wielding French flags, 4 men and a smoke machine.

The project was named Sea of Hull, and was commissioned by Ferens Art Gallery in recognition of the following year's City of Culture events.

They held circular Mylar mirrors over their heads and reflected light at the city to expose what they view as the naked truth about Republicans.

In July 2018, Tunick photographed almost 500 men and women draped in sheer red cloths on top of a Woolworths supermarket building in Melbourne, Australia.
