Brrrrrrrrrrrrrr! That's what it takes to produce a halo around the sun!
I took this shot this morning just for YOU!
The ring is caused by sunlight or moonlight being diffracted as it passes through cirrostratus clouds that are usually at altitudes above 20,000 feet. Cirrostratus clouds are composed mostly of small ice crystals that spread out into a thin layer. They are sheet-like, and the sun and moon can be seen through them easily.
Ice at 20,000 feet. Brrrrr.
Now, what happens if I way push the gama curves? Sometimes over processing distorts an image and sometimes over processing brings out an unexpected detail.
Same image as above but way over processed:
What's going on? Like a telescope at high power, you're seeing inside the camera. That's the aperture. It's like a hole in the sky.
