In 2017, a good portion of the United States had the rare opportunity to experience a solar eclipse. Boise, Idaho wasn’t in the “path of totality” for the moon blotting out 100 percent of the sun, but we peaked just shy of it at seeing 99.5 percent of the sun covered.
A pinhole camera is the most simple image-projection technology there is. You can use a thumbtack to punch a hole in card stock, hold that card under a direct light source, and a tiny, exact image of that light source will be projected on the other side of the hole.
Sunlight filtering through the branches of trees will create a field of crescent-shaped light on the sidewalk below it. It’s the pinhole camera effect, multiplied naturally hundreds of time underneath each tree. Each gap in the leaves acts as its own pinhole, so you see an image of the eclipse in each of those gaps.
Where were you during the eclipse on August 21, 2017?
