Caption: The image shows multiple pinhole projections caused by a canopy of tree leaves during the partial solar eclipse that accompanied the annular solar eclipse of 2005 Oct03. The image was taken at St. Julian's, Malta.

Features:

1. The gaps in a canopy of tree leaves provide pinholes. Pinholes can be any shape. They just have to be small compared to and remote from the image you are projecting. Each bit of the pinhole provides a faint image and, with the given conditions, these all overlap nearly exactly to create one bright image. The closer the images are to the pinhole, the less exact the overlap. Inexact overlap causes blurring.

2. Ordinarily, under a canopy of tree leaves if there are gaps for the sunlight to filter through, you will see multiple images of the full Sun. You just never noticed have you?

   But during partial solar eclipses, you see multiple images of the crescent Sun which looks weird---even if you can't figure out why.

3. In fact, partial solar eclipses are often NOT spectacular events and may NOT even be noticed. If you were NOT informed that they were occurring, you may NOT be aware of them at all.

   Certainly, the Sun disk has a convex bite taken out of it, but without specially viewing equipment (e.g., a guaranteed-safe solar filter or pinhole projections setup) you CANNOT see that since you should NEVER look at the Sun whenever any part of the solar photosphere is visible.

   The sky during partial solar eclipses will just look a bit dimmer than usual as if there were some extra cloud cover and if there is cloud cover the dimming is really hard to notice. Of course, if the sky is very clear, the dimming is quite striking especially the closer to totality the partial solar eclipse is.

   There is also a cooling effect that can be quite striking especially the closer to totality the partial solar eclipse is.

4. But one spectacular thing that can be seen without special equipment is the aforesaid the multiple images of the crescent Sun under a canopy of tree leaves. The spectacle is better the closer to totality you are---the crescents are more crescenty.

   If you were unaware of the partial solar eclipse, you might wonder "what the heck".

   The multiple-crescent effect was quite noticeable under the canopy of tree leaves of the UNLV boulevard during the annular solar eclipse that whipped through the western USA on 2023 Oct14. So were the sky dimming and cooling effects.
