Shooting during the Solar Eclipse

| ->> I am not wanting to know how to shoot the Solar Eclipse but how to shoot during the eclipse. I have some big groups about 150-175 that I am going to be doing during the time of the eclipse. I was told that it was going to go almost completely dark where I will be located (95.5%) is this correct? |

->> This is something I've had a lot of trouble figuring out, even though I've photographed a partial eclipse before. My understanding is this: the percentage of the sun covered and the brightness are not really related. 100% of the sun covered does equal 100% of the sun's light blocked, yes. But even 0.5% of sunlight is still very bright - I've seen figures that claim it's 10,000 times brighter than the full moon. What I wish I could find is precise numbers on that - say, just as a random example, does 99.5% coverage equal perhaps 30% light? Or heck could we find a resource that measures it in f-stops? The closest description I've found is this:

Google might provide other answers although I've not had a lot of luck. I've seen enough to know I want to get into the path of totality, which is fortunately only about 15 miles from me.
We had a partial here five years ago that was about 84% coverage, and it didn't get darker at all - maybe the tiniest bit. My guess is at 95-ish% it's going to be slightly dimmer than usual - a stop or two, perhaps - as though a smallish cloud drifted in front of the sky but not diffuse at all, strong shadows just like full daylight. |

->> If I'm interpreting your query correctly, you want to figure out how to expose properly while the eclipse is happening. You won't be shooting the sun, just the groups of people, etc ... ?
So, I would shoot aperture priority, used in conjunction with speedlights and exposure compensation. Gradually adjust ISO when needed. |

| ->> Andrew, You are correct. I will probably shoot manual and then increase the strobes, and also will position strobes behind the subjects to give a rim light. |
