Sun’s path June to December

“Last June I placed some photographic film into a tin cannister with a small hole punched into its side. The tin cannister was then attached to a clothes pole in my backgarden and left.

This afternoon I fetched the cannister and took the photographic film out. My son John scanned the photographic film and with the aid of some image software made the image negative.

The result is the picture above.

The picture clearly shows the path of the sun through the sky over the last six months.

I believe you can see we didn’t have a great summer by the broken lines at the top.”
