Here is another Solstice-to-Solstice image of the Sun’s path across the sky taken with a tea-caddy tin pinhole camera and FLAT film. The beer can pinhole camera uses film folded around the inside of the can and leads to a more distorted final image. Camera opened on 18th June 2011 (3 days before Summer Solstice) and closed on 21st December 2011 (one day before Winter Solstice).
The straight line towards the left of the image is the edge of the roof of the house across the road. You can see plenty of trees along my southern horizon. The two light dome-shaped regions are the two New Forest observatories in my garden.
Nice to see this rectilinear projection of the Sun trajectory. Most examples found over the Net are cylindric projections (they use beer cans as you mention). I was writing down the rectilinear equations and clearly the paths in the summer solstice diverge from the horizon.
