This is the photo from my camera, Owen's can be seen in my other album.
The lines across the top are the sun as it moves across the sky each day. The low lines being back in December and the higher lines more recently. Solid lines are sunny days, broken lines are patchy cloud and dark gaps are cloudy or overcast days or weeks.
My camera was pointing slightly down and I can pick out a few features in our garden, such as the trampoline, sand box and wall around the lower lawn.
The pale silhouette above the tree line in the middle is how high the trees were until we lopped the tops off them a couple of months ago.
This is fascinating!
