In the wake of Hurricane Katrina in 2005, Polidori photographed the damaged homes and buildings of New Orleans, and documented the city's early restoration in 2006. Published as "After the Flood" (2006) by Steidl Verlag, many of these images were also exhibited at New York's Metropolitan Museum of Art as "New Orleans after the Flood", a popular and well-attended exhibition. Exhibitions of "After the Flood" were also mounted in London, Venice, and Toronto, as well as in New Orleans. During this time, Polidori continued to document the restoration of Château de Versailles and these photographs, published in the three-volume "Parcour Muséologique Revisité" (2009), were included in his retrospective exhibition at the Musée d'art contemporain de Montréal. Polidori returned to Beirut in 2010 where he photographed the damaged rooms of the famous Hotel Petra, abandoned during Lebanon’s civil war. The following year, he traveled to Paris to photograph the stored art collection of Yves Saint Laurent (designer), and to Venice to photograph the fashion label Bottega Veneta's fall 2011 campaign at the Palazzo Papadopoli. From 2011 to 2015 Polidori also revisited and rephotographed Rio as well as Mumbai, including Dharavi's industrial street facade in a series of tracking shots. Exhibited as composite panoramic murals at Paul Kasmin Gallery (New York) in September 2016, these images were also published in the accompanying volume "60 Feet Road" by Steidl Verlag.
