The sun came back. It was an interesting morning, though!

Went scout camping, for a long weekend, with the whole family.
2:37 of totality, perfect weather, incredible experience.
I will travel for the next one, seriously great time, really special.

I was in the 99.1% part, and I figured it would be considerably more dramatic than it was. Pretty crazy that 0.9% of the output only gets it down to the level of a slightly overcast day. It was pretty underwhelming. The crescent shadows were pretty cool.
Dean, Don't forget that your irises opened up as it got dark, lessening what you perceived of the range of illumination.
This was starkly visible after totality when the cameras monitoring the sun suddenly switched their iris setting to be ready fkr sunshine again. The bright corona changed to a hardly visible sliver of light.
An audio parallel: imagine hearing music that gets quieter... and your ears become more sensitive!

Was 71% coverage here, assumed it would darken a bit outside. It did not, not a lick. Was not impressed at all. VERY disappointing. However, the sun didnt blister your skin for a few moments and the temp did drop, so what was nice. Other than that, Waste of time. Completely.

They should have used better filters on the cameras, if they used them at all.
The audio effect can be caused by using compressor/limiters.
My mechanic told me, "I couldn't repair your brakes, so I made your horn louder."
We had cloudy sky and occasional open areas, but it wasn't easy to see the Sun directly and that didn't last for long. It was still easy to see when the Moon crossed the center of the Sun, though- we were in the 87% range.
I have seen several partial eclipses so I didn't get all gooey about it, but I saw a video about Sedona, AZ and the wackos who went there to capture some of the energy from the vortices. Yeah, put THAT in a bottle.

Yes, it did. Your body has GREAT autoirises.

I'm talking about iris settings. What filters would they use instead of making an iris adjustment?* Filters usually limit the wavelengths and/or polarization of light, while iris adjustments don't mess with that at all, but instead limit the amount of light -- of the original spectral composition -- allowed into the camera.

Not really. He experienced very little change in apparent light level reaching his eyes, which I think was due to his irises opening as the light diminished. I made a parallel between that and some imaginary action of the ears that might make quieter sounds become easier to hear.
Compressors and limiters do not change how the ears work, so they're already off the table. In addition, their action is to limit the upper part of the dynamic range, not to expand sensitivity in the lower part of the dynamic range.
*Edit: I realized that the large amount of light attenuation needed to get a proper exposure with a camera probably would require a filter, just as our eyes need a filter to look at the sun. The smallest camera iris I've run across was f22, and I bet you'd need something like f200 -- hey, a pinhole! -- if only an iris was to be used.
The problem was not that the filter wasn't good. It was that they slapped it in place, changing an image of the black disc of the moon with corona around it into no image at all except for a dim crescent, hardly visible at all.

Made it a long weekend & stayed with a buddy in Charleston SC. We got 100% of the eclipse but it was really cloudy. The clouds broke up just enough for a matter of seconds during totality that we really got to see it. Even with the clouds it was probably the coolest thing I've ever seen. We saw stars & planets & it got plenty dark & considerably cooler as things progressed.
