Guli discovered the secret of light three years ago while being punished to stand. She was staring at a photo of her parents pressed under a piece of glass. The sunlight on the plateau and the reflection from the snow made the photo dazzlingly bright. She stared at the photo in a daze, and after an unknown length of time, she closed her eyes, only to be amazed to find that the image of the photo was imprinted in her vision. It became more apparent when she faced the sunshine, though it would fade after about a week. She began using shards of glass she found while herding to enhance the imprint of the photo.She has been doing this for a year, and now the image can last for a full month without fading. I photographed the image already imprinted in her eyes and superimposed it above, hoping viewers could also see the vision she longs to behold every time she closes them. In an era of rapid technological and military advancement, what is happening here represents a kind of "regressive evolution" of technology. The children's method is essentially a reversion to the origins of photography, using optics to fix images. This forces us to reflect: in extreme environments, what constitutes technology? Whose technology counts? And what have we sacrificed in the name of so-called progress?
