Pinhole Cameras

The annular eclipse yesterday was magical to say the least. At Abilene State Park it was in the 88% coverage zone.

Using the solar safety glasses I took time to gawk at the sun and moon.

Then between taking photos with the Canon, we played with the pinhole cameras, humanmade and nature’s lens. The grease strainer was not as sharply focused.
It was lunch time so of course we posed a peanut butter sandwich with the crescents.

Cookies too. Afterwards we thought we should have taken a bite out the cookie with the crescents. Hindsight, eh. 😉 We were all hungry and didn’t think of that at the time. LOL.

Here was the view in the Canon view display.
The pinhole camera using the aluminum foil worked pretty good.

However the pecan trees above were the best. Claire observed that the nearby cottonwood tree was not a very good pinhole camera.

Briar’s snout!

Claire’s straw hat was excellent!

Indeed Briar was a very photogenic background!

Grease strainer.

Again the grease strainer. However the images projected seemed almost 3D. Weird!

Back home report. This red arrow points to the drop in our solar production at our house when the eclipse occurred.

One final note about the eclipse yesterday. I actually may have seen a shadow band. So I had never heard of the phenomenon before until this morning while surfing on the internet. Shadow bands are thin, wavy lines of alternating light and dark on surfaces. Yesterday when I had just begun to look for the crescent shadows when I had noticed on the picnic table it was not doing the crescents. Of course I was a bit annoyed at the time. However moments later the crescents were there. To capture a shadow band it is apparently best to take a movie. Certainly for April’s eclipse, I will definitely be looking for the shadow bands.

What are the beautiful, crescent-shaped shadows that occur during an eclipse?

  1. The hat, Briar and the pecan trees are awesome. We noticed that the Live Oak wasn’t great but Cedar Elm was was slightly better. Trees are so lacking in leaves that it didn’t display like i thought it would. I tried a piece of paper with a hole puncher size holes. The light was perfect circles at all times. Are those holes too big?

    1. Kathy, we tried with big plastic storage cartoons. They had holes which are about 1.5 inches across. Didn’t work either. Jim suggested that I would need to hold it up real high for it too work. We were not able to hold it higher than our reach. The grease strainer we also had to hold up higher compared to the foil. Fun stuff! Thanks!
