The wonders of technology never cease to amaze as London-based artist Daniella Zalcman unveils her latest project, the aptly titled “New York + London: A Collection of Double Exposures.” Originally developing the idea during her last month in New York City, Zalcman took over 100 smartphone photographs of the streets in the Big Apple. She then used various smartphone apps such as Instagram to delicately superimpose the pictures over images of London’s alleyways. The result is a beautiful ode to the similarities between two of the world’s greatest cities. Zalcman, whose work has been featured in Vanity Fair, The Wall Street Journal and Sports Illustrated, is currently raising funds via Kickstarter to produce a photo book of her work. The full set can of images can be seen over at Yatzer.
