Sunburns (fade), burnt hole through/with sun exposure on b/w photo paper, each 12cm x 17.5cm, 2015

I went outdoors with a stack of light-sesitive b/w photo paper in a black bag. I took the stack out, placed it on the ground and focused the sun's rays on the top sheet with a lens. Over the course of a minute the hole burned ever deeper and the sun's rays seeped through each sheet. After developing them, the gradient emerged. Scroll down for details.
