Would you like to walk on the Moon? Just stroll under a leafy tree on a moonlit night! You’ll step on hundreds of images formed by moonlight leaking through tiny gaps between overlapping leaves! These "natural pinhole images" are upside down, like the image of the Full Moon in the center. The surrounding images at other phases are reoriented with north up. All these images were obtained under a small oak tree in the author’s backyard. At the linked website, click on each one to compare with NASA images from the Lunar Reconnaissance Orbiter. Differences are caused by the quality of the specific pinhole, exposure time, and the color response of the camera. Similar images of the Sun are often shown during eclipses. However, the Moon is about a million times fainter, requiring longer exposures but not too long or else its image would be blurred as the Moon moves across the sky. Even so, your dark-adapted eye can still see broad features (dark maria), and even a cellphone camera will reveal finer details like the region around the bright crater Tycho. The website provides an animated sequence over a range of phases (November 2023 to March 2024). To emphasize their natural character, these images have not employed sophisticated processing techniques.
Details: Canon EOS 80D, 1-10 sec exposures, ISO 12800
