Here is some of my pinhole photography. I make pinhole cameras using old soda cans or mint tins. I load them with light-sensitive photo paper and set them up outside, typically on tree branches. These images are a few days to several month long exposures. Once complete, I scan the paper digitally and invert the colors. The white lines that can be seen in the sky is the sun’s path. As the sun gets higher in the summer and lower in the winter, you can see the different lines from where it travels across our sky.
