stability of 'sunny 16'

[DREW WILEY]

I wonder how many people use "Sunny 16" for photographing a noonday solar eclipse?

If you wanted to photograph a landscape under a solar eclipse, seems you could just multiply sunny 16 by the percentage of uncovered sun.

No, because the corona of the sun is brighter than the sun in general -
and how would you measure it anyway since an eclipse is gradual? Photographers have worked it out by trial and error, and one can look up their results, or consult actual astronomers. I was simply being facetious, even mentioning it. I didn't even set up a camera for the lunar and solar eclipses here, though I did view them.

Next month, the herds will be trampling themselves to death crowded into a particular parking lot in Yosemite for many hours, awaiting the few minutes a year the sun sets behind Horsetail Falls, creating the natural (rather than artificial) Yosemite Firefall. Many will be cellphone idiots, others expensively equipped and having done their homework in terms of exposure. The weather will determine whether anyone gets anything at all. I have no interest in being there, and adding one more shot to the tens of thousands before. My memorable event was hacking my way up an ice cone beneath the fall, leveling off the top with the ice axe, and taking a sideways shot of El Capitan with my Sinar. I'm pretty sure nobody else has ever taken a shot like that, or ever will again. It was risky enough; and 4x5's aren't exactly standard climbing accessories.
