This image of the blood moon and white pine tree in Georgian Bay was taken in the late 70s, as well as in January 2019. The original was a double exposure on Kodachrome 25 of the tree first and, a couple of hours later, the moon.
In January 2019, we had this gorgeous blood moon on a super cold night. I think it was -20 C. Because the moon turned out really well, I replaced the moon in the scan of the old slide with the blood moon.
However, in the blood moon image, stars were clearly visible. That was a problem. So I added stars separately to the original late 70s image. The digital age is magical.
