“Solargraph Showing the Sun’s Motion over 53 Days”

This is Solargraph image #4 that I have done. It was taken with a "Pop Can" Pinhole camera from my backyard here in Albany, Missouri. The image was taken from October 26, 2022, through December 18, 2022, equaling fifty-three days. That makes the exposure 4,579,200 seconds long. The view is looking south with the east at the left. The old locust tree, a constant feature in many of my recent photographs, is prominent in the center foreground.

The sun's path across the sky (53 days' worth) during this exposure can be seen as the bright curved lines that stretch across the image. The sun rises to the left in the east and sets to the right in the west. The gaps in the lines are caused by cloudy days when the sun was behind clouds and wasn't recorded on the photo paper.
The sun reaches its highest point each day at local noon behind the tree. In this instance, the sun’s path is at its lowest in the sky for us here in the Northern Hemisphere. This exposure was taken during Fall ending near the first day of Winter when the sun only reaches about 26 degrees above the southern horizon.

The pinhole camera was made from a Ginger Ale can and sat outside taped to a clothesline pole during all types of weather. An image was accomplished by placing Ilford photographic paper in the can and exposing it through a pinhole for fifty-three days. After the exposure was over, I scanned the photographic paper into the computer with a flatbed scanner.

A few basic Photoshop tricks were performed to bring out a few details. The color seen in the photo is not from the blue sky but is from the scanning process. I’ve posted an image of the original photo paper negative on my Facebook Page.
