Why Solar Eclipses Create Those Crescent-Shaped Lights

The video discusses the fascinating crescent-shaped lights seen during solar eclipses, caused by the pinhole camera effect. This effect occurs when light passes through gaps in tree leaves, projecting upside-down images of the sun on the ground. The sharpness of these images is enhanced during an eclipse due to reduced ambient light and the narrowing of the sun's visible portion. The video also highlights that similar pinhole images can be observed at night with LED streetlights. Overall, solar eclipses reveal intriguing natural phenomena that are present around us all the time.

Explain why the images created during a solar eclipse are sharper compared to normal light patterns.

How can one observe pinhole images at night, and what causes them?
