Besides leaving pinhole cameras out for six months between the solstices, I also like to leave them out for the few days of the actual solstices.
I left this camera in Moab, Utah facing a small pond December 18-25 which were the days that the Sun was at its lowest track across the sky.
Again, homemade pinhole camera, very expired Kodak Poly Black and White photo paper.
Scanned, inverted and adjusted contrast.
Happy New Year everyone!
