One of the great drawbacks of paint cans as pinhole cameras is that they lack viewfinders. So in this first solargraphy test, my aim was a little off: a little too far to the south, not enough to the east. But I did catch a bit of the sun (that green-yellow streak on the left) rising behind some trees as seen from the post under a bird feeder in my front yard for about 2 weeks in late May.
So the technique works. The paper (a 4×10-inch half-sheet of Ilford Multigrade FB semi-matt) came out of the can (in a darkened room) with a faint, low-contrast, magenta-toned, negative image already visible. No chemical processing required. I scanned it into Photoshop, inverted the image, and adjusted the curves to increase the contrast and reduce the strong green cast.
I currently have 3 more paint cans gathering photons in secluded locations around California. Results will be posted in due course.
