"The weather was cloudy and rainy all day. However, in the picture, the sun has been seen visibly a few times in the sky. I was wondering if something could be visible by the solargraphic method."
"The pinhole camera was a black paper box 10x10cm. The exposure was about 10 hours. After scanning the paper negative I inverted it to the positive image in a computer. The passing time can be seen as white spots in the solargraph."
