“It’s a photobooth where you snap your own photo” The Self-Portrait Project (SPP) is an interactive art, social change, and commerce project whose mission is to empower people in the creation and curation of their own images. SPP photo kiosks are located throughout New York City and at events nationwide. Locate one and control the kiosk camera using your phone and this app. Capture Once you’ve connected, snap pictures and see them instantly on your phone. Share Share photos with friends, and choose your favorites to contribute to the Self-Portrait Project. Browse Sift through thousands of photos in the SPP archive by date, place, or keyword. … Created in 2009, the Self-Portrait Project is a photo-based, interactive archive project that seeks to capture the zeitgeist of New York City and beyond. A SPP kiosk utilizes a two-way mirror with a camera set up behind it. Standing in front of the mirror, the participant uses her/his phone as the remote trigger. The participant chooses how and when to shoot her/himself. In the simple act of letting the model be photographer, the dynamic of the potential photo changes and therefore the final image. Giving someone who is accustomed to having their picture "taken" the opportunity to document their own likeness under their own terms produces images that address issues of vanity and insecurity, empowerment and self-awareness, superficiality and substance. As the photographer *and* model, you are wholly responsible for the images you create of yourself.
