Driving record solargraph, a negative view
Fixed a jar lid pinhole camera on roof of my car and drove 150 km on a sunny day (2017-05-06). Road trip involved about 40 turns at crossroads and a few stops that left good landmarks in the image.
Reading of this image is odd and interesting:
- Center is zenith
- Time goes radially from center to the sides
- Each 90 degree turn of car makes a circular 90 degree line in image
- Prolonged time when car is standing results in deep linear burns by the Sun moving slowly in the sky
- Prolonged driving in one direction on flat terrain makes few lines but deeper burns.
- Hills or pits on the road result in zigzag pattern.
