My 4-camera 4K eclipse video and about traffic from the Eclipse

The Eclipse of 2017 caused dire traffic warnings, even from myself. Since a total eclipse is the most amazing thing you will see, and one was coming to a rich country where almost everybody owns a car, and hundreds of millions live within a day's drive -- I wondered how we would not have horrendous traffic. (You can see my main Eclipse report and gallery here or see all my Eclipse articles.)

Also look out below for a new 4K video I made from having 4 different video cameras running around the eclipse. I have started you 3 minutes in for the short-attention-span world, but you might also enjoy the 3 minutes leading up as the excitement builds. Even on an HD display, be sure to click through to Youtube to watch it full screen.

As described, the 4 cameras are two 4K cell phones facing forward and back, plus an HD video from a 1200mm superzoom camera and snippets of 4K video and stills from the main telescope and Sony A7rII.

The big places for predicted bad traffic were central Oregon, because it was the place with the best weather that was closest to everybody from Seattle to Los Angeles, and areas of South Carolina which were closest for the whole eastern seaboard. At a popular Eclipse site, they had a detailed analysis of potential traffic but in many cases, it was quite wrong.

The central Oregon spine around the tiny town of Madras did get really bad traffic, as in reports of 4 to 6 hours to get out. That was not unexpected, since the area does not have very many roads, and is close to Washington and relatively close to California. At the same time, a lot of traffic diverted to the Salem area, which got a nice clear sky forecast. It has an interstate and many other roads. Planning ahead, Madras was the best choice because the weather is much more unpredictable west of the Cascades. But once the forecast became clear, many people from Seattle, Portland and California should have shifted to the more populated areas with the larger roads.

I decided, since it was only 2 hours more driving to Weiser (on the Oregon/Idaho border) but much less traffic, to go to the Snake River valley. It was the right choice -- there was almost no traffic leaving Weiser. In fact, Weiser did not get overwhelmed with people as had been expected, disappointing the businesses. Many thought that a large fraction of Boise would have tried to get up to that area, but they didn't. We actually wandered a bit and ended up over the river in a school field in Annex, Oregon.

There was no problem finding space, even for free.

This is a pattern we've seen many times now -- dire predictions of terrible traffic, then almost nothing. It turns out the predictions work too well. The famous Carmageddon in Los Angeles never materialized -- even with a major link cut, traffic was lighter than normal.

This is, in turn a tragedy. It seems a lot of people did not go see the eclipse because they were scared of bad traffic. What a great shame.

4K Video

At my sight I had 4 cameras recording video. I set up two cell phones, both able to do 4K, looking at our group from in front and behind. The one behind I put in portrait mode, almost capturing the sun, to show that view, while the one in front showed us looking at the eclipse and also the shadow approaching on the hills.

Photo gallery from 2017 total solar eclipse

I was just outside Weiser Idaho, a small town on the Snake river, for the 2017 Eclipse, which was an excellent, if short, spectacle which reawakened U.S. interests in total eclipses. They are, as I wrote earlier, the most spectacular natural phenomenon you can see on the Earth, but due to their random pattern it's been a long time since one has covered so much of the world's richest country.

For me, it was my sixth total eclipse, but the first I could drive to. I began this journey in Mexico in 1991, with the super-eclipse of that year, which also was the last to visit the United States (it was visible on the big island of Hawai`i.) Since then I have flown around the world to the Curacao area, to the Black Sea, to the Marshall Islands (more photos) and French Polynesia to see other total eclipses. And I will continue to do so starting with 2 years from now in Argentina.

I recommend before you read that you enjoy my Gallery of 2017 Eclipse Photos in HD resolution. When going through them I recommend you click the "i" button so you can read the descriptions; they do not show in the slide show.

Why it's impossible (today) to photograph

I did not photograph my first eclipse (nor should anybody) but every photographer, seeing such a spectacle, hopes to capture it. We can't, because in addition to being the most spectacular natural event, it's also the one with the greatest dynamic range. In one small field you have brilliant jets of fire coming off the sun, its hot inner atmosphere, its giant glowing outer atmosphere and a dimly lit dark sky in which you can see stars. And then there is the unlit side of the moon which appears to be the blackest thing you have ever seen. While you can capture all these light values with a big bracket, no display device can come close to showing that 24 stop range. Only the human eye and visual system can perceive it.

Some day though, they will make reasonable display devices that can do this, but even then it will be tough. For the eclipse covers just a few degrees of sky, but in reality it's a full 360 experience, with eerie light in all directions and the temporary light of twilight in every direction. Still, we try.

In the future, when there is a retinal resolution VR headset with 24 bits of HDR light level ability, we might be able to show people an eclipse without going to one. Though you should still go.

Moment of 3rd contact

That's why these photographs are so different. Every exposure reveals a different aspect of the eclipse. Short exposures show the prominences and the "chromosphere" -- the inner atmosphere of the sun visible only at the start and end of the eclipse. Longer exposures reveal more of the giant corona. The fingers of the outer corona involve 2 or 4 second exposures! The most interesting parts happen at 2nd and 3rd contact (the start and end) and also have many aspects. About 1/60th of a second shows the amazing diamond ring by letting the tiny sliver of sun blow out the sensor to make the diamond, as it does to the eye.

Time to rename the partial eclipse

One thing that saddens and frustrates me is that all of this is only visible in a band less than 100 miles wide where the eclipse is total. Outside that, for thousands of miles, one can see (with eye protection) a "partial eclipse." They both get called an eclipse but the difference is night and day. Yet I think the naming makes people not understand the difference. They think a "90% partial eclipse" is perhaps 90% as interesting as a total eclipse. Nothing could be more wrong. There are really three different things:

  1. The total eclipse, the most amazing thing you will ever see.
  2. The >98% partial eclipse (and annular eclipse) which are definitely an interesting event, but still just a tiny shadow of what a total eclipse is.
  3. The ordinary partial eclipse, which is a fun and educational curiosity.

I constantly meet people who think they saw "the eclipse" when to me and all others who have seen one, only the total eclipse is the eclipse. While the 98% partial is interesting, nobody should ever see that, because if you are that close to the band of totality, you would be nuts not to make the effort to go that extra distance. In a total eclipse, you see all that the partial has to offer, and even a few partial effects not seen except at 99.9%

A wider angle HDR with deep corona

As such, I propose we rename the partial eclipse, calling it something like a "grazing transit of the moon." An eclipse technically is a transit of the moon over the sun, but my main goal is to use a different term for the partial and total so that people don't get confused. To tell people in the partial zone "you saw a transit, hope it was interesting" while telling people in the total zone, "You saw a solar eclipse, wasn't that the most amazing thing you've ever seen?"

Automating the photography

This was the first eclipse I have ever driven to, and because of that, I went a bit overboard, able to bring all sorts of gear. I had to stop myself and scale back, but I still brought 2 telescopes, 4 cameras, one long lens, 5 tripods and more.

Your eclipse guide (with the things not in many eclipse guides)

I will be heading to western Idaho this weekend to watch my sixth total Eclipse. That makes me a mid-grade eclipse chaser, so let me tell you some important things you need to know, which are not in some of the other eclipse guides out there. For good general sites look at places like NASA's Eclipse Guide which has nice maps or this map.

Totality is everything

The difference between a total solar eclipse and a partial one -- even a 99% partial one -- is literally and metaphorically night and day. It's like the difference between sex and holding hands. They are really two different things with a similar sounding name. And a lunar eclipse is again something vastly different. This does not mean a high-partial eclipse is not an interesting thing, but the total eclipse is by far the most spectacular natural phenomenon visible on this planet. Beyond the Grand Canyon, Yosemite, Norway, etc. So if you can get to totality, get there. Do not think you are seeing the eclipse if you don't get into the zone of totality.

People debate about how deep into totality you want to be

Many people seek to get close to the centerline of the eclipse. This provides the longest eclipse for your area. You will only lose a modest number of seconds if you are within 15 miles of the centerline, so you don't have to get exactly there, and in fact it may be too crowded there.

On the other hand there are those who deliberately get close to the edge, giving up 30-40% of their eclipse time in order to see more "edge effects." Near the edge, the edge effects are longer and a bit more spectacular. In particular the diamond ring will be a fair bit longer, and you may see more prominences and chromosphere for longer. If this is your first eclipse, I am not sure you want to get too close to the edge. But try any of the map web sites that will tell you your duration, and get somewhere that has within 30-40 seconds of the centerline time.

You look at the total eclipse with zero eye protection

You've been hearing endless talk about eclipse glasses and how well made they are. Eclipse glasses are only for the boring partial phase. They give you a way to track the progress of the moon while waiting for the main event. Once totality is over, everybody packs up and does not even bother to watch the 2nd half of the partial eclipse, that's how boring the partial part is.

But don't be one of those people who, told about the danger of eclipses, does not watch totality with your bare eyes. In fact, use binoculars in addition to your naked eyes, and perhaps a short look through a telescope -- but not during the diamond rings or any partial phase.

Update: There is a nice large sunspot group that should still be there on Eclipse day, making the partial phase more interesting to those with good eyesight.

In totality you are looking not at the sun, but its amazing atmosphere -- the "corona" -- full of streamers, and many times the size of the sun or moon. You may also see jets of fire coming off the sun, and at the start and end of totality you will see the hot red inner atmosphere of the sun, known as the chromosphere.

If you are crazy enough to be outside the total zone but close to it, you sadly still can't look with your bare eyes at any part of the eclipse.

There are some cool things in a 99% partial eclipse (which you see just before and after totality.)

An eclipse is most glorious in the sky but a lot of other things happen around it. As it gets very close to total you will see the nature of the sunlight change and become quite eerie. Shadows of trees will turn into collections of crescents. About 20-60 seconds before and after totality, if you have a white sheet on the ground, you will see ripples of light waving, like on the bottom of a giant swimming pool. And the shadow. You will see it approach. If you are up on a mountain or in a plane this will be more obvious. It is going at 1,000 to 2,000 miles per hour.

Amazing eclipse at Enewetak, Marshall Islands

The total eclipse of the sun is the most visually stunning natural phenomenon there is. It leaves the other natural wonders like the Grand Canyon far behind. Through an amazing set of circumstances I got to see my 4th on Enewetak, an isolated atoll in the Marshall Islands. Enewetak was the site of 43 nuclear explosions including Mike, the first H-bomb (which erased one of the islands in the chain.)
