Fashion and art photographer Heji Shin’s self-portrait at 52 Walker gives and withholds information, depicting a holographic image of her brain made with a special MRI technique that pictures neural networks in brilliant color. Though the scans allow us to literally see her brain, more telling about Shin’s thoughts are her studio photos of pigs – their faces full of character – that appear on the surrounding walls. Titled ‘Big Nudes’ after Helmut Newton’s boldly-posed 1981 images of nude women, the images question how both photos and their subjects are consumed. (On view in Tribeca through Oct 7th).
