Personal Aerial Photography

A few thoughts from someone who has been doing it for a long time.

I’ve been doing aerial photography since I began flying helicopters, way back in the late 1990s. At first, it was a few digital images shot awkwardly with my left hand while my right hand was busy on the cyclic. Later, I went through a variety of different cameras mounted in and on the helicopter, some set to automatically shoot whatever was in front of them and others with limited control from inside the cockpit. I had a POV.1 camera in 2008, which I replaced with a GoPro Hero in 2010. Since then, I’ve had a variety of GoPros, right up to a GoPro 3+. (Even I get tired of throwing money at new versions of hardware.) I’ve created numerous still and video images from my helicopter, some of which still amaze me.

Great Salt Lake
This is one of my very favorite aerial photos: the north end of the Great Salt Lake, shot with a GoPro 3 mounted on the nose of my helicopter as I flew it south to Arizona last autumn. The camera was set to time-lapse mode, shooting one photo every minute. We were probably about 700 feet up here.

But the point of this discussion is this: I’ve been looking at the world from a different point of view for about 20 years now. It’s not the same point of view as an airliner cruising at 29,000 feet and 500 mph. And it’s not the point of view of a private plane cruising at 1,500 feet and 140 mph. It’s the point of view of a helicopter, usually cruising at an average of only 500 feet at 90 miles per hour, with the ability to stop, make sudden turns, or descend for a closer look.

Pilots get used to seeing the world from this different perspective. After a while, it isn’t anything special. We can get a feel for how different things might look from the air: a canyon, a river, a farm, a junkyard. That doesn’t mean it gets boring — it doesn’t. But it does mean that we don’t see anything special about it anymore.

Kind of sad, isn’t it?

That’s one of the reasons I like flying with first time passengers. I get a reminder of what it’s like to see things from a new perspective.

But I was reminded again about the novelty of seeing everyday things from above when I watched a documentary on Lynda.com called “Flight Club: Drones and the Dawn of Personal Aerial Imaging.” Listening to the people explain how they felt when they saw these low-level aerial images really helped me understand just how amazing aerial photography is, especially to folks that don’t have a helicopter at their disposal — which, admittedly, is most people.

Folks who know me well know how anti-drone I was when they first started appearing on the scene a few years back. But what convinced me that they were serious photography tools is the quality of the images they produced and the ease at which an operator could get them. I dove into drone photography last winter with the purchase of a Mavic Pro and will be doing a lot more of it in the months to come.

If you are curious about drones for aerial photography, I highly recommend you spend 25 minutes or so watching the documentary I saw last night. I think you’ll enjoy it and learn a lot about why people are so excited about it.

If you do watch, let me know what you think.

Killer Floods

A review with a backstory.

Last summer, I did a flying gig that started in Spokane and had me flying over a good portion of the state. The client was a video production company based in the U.K. that was working on a NOVA documentary about the ice age floods, which are often referred to as the Missoula Floods.

If you don’t know anything about the Missoula Floods, here’s the short version. Millions of years ago, when the Cascades were a chain of active volcanos, they laid down layer after layer of lava that became (mostly) basalt rock. The Ice Ages came and a sheet of ice stretched from the North Pole down into the northern United States. In Montana, the ice sheet formed a dam across the mouth of a valley and huge volumes of water accumulated behind it. Over time, the ice dam was eroded and broke free, releasing all that water very quickly. It came downstream, across Idaho and Washington State, carving out some very interesting canyons and other formations. Then the ice dam was created again and broke again and created again and broke again. This cycle happened at least 15 times, depending on who you talk to, starting about 16,000 years ago. It explains the modern geology of Central Washington state’s coulees (those carved canyons), potholes, dry waterfalls, and so-called Scablands. You can read more about this in Wikipedia. Or you can just watch the documentary I’m reviewing here.

The best way to get an idea of the massive scale of the hydrologic action resulting from the Floods is from the air. Sure, you can take a hike into a coulee or to the top of Dry Falls and look around, but it isn’t until you get a few hundred feet up that you realize just how enormous these places are. So the film crew looked for a helicopter with a Cineflex camera mount. Of course, there aren’t any of those outside a big city and they did have a budget so bringing one in was not an option. They did, however, find my helicopter company, Flying M Air, which, at the time, owned a Moitek gyrostabilized camera mount (which I’ve since sold).

I should mention here that this is the one and only time that damn camera mount got me a flying gig. I bought it to increase my aerial photo business and very seldom used it. I charged a fee for its use and it probably finally paid for itself sometime in 2014; I’d owned it since 2009. It was a beautiful piece of equipment, exquisitely hand made right here in Washington State, but it weighed a ton and took 30 minutes to assemble and another 20 minutes to break down. I hated dealing with it, despite the $500 per use fee I charged. Packed in two huge Pelican cases — one for the mount itself and one for the three Kenyon KS-8 gyros that went with it — it took up space and gathered dust on my garage floor. I sold it to an LA-based pilot for just $5K this past summer. What a steal. The gyros alone were worth more than that — but I don’t miss it one damn bit. It was not one of my best asset acquisition decisions.

The Flights

Turns out that they needed a videographer who could use the mount and had appropriate equipment to mount on it. I turned to Charley Voorhis of Voortex Productions, one of the two local video companies I’ve worked with. Charley has some impressive equipment — I think he brought one of his RED cameras for this gig — and lots of experience with the mount. (I almost wish he’d bought it.) Then I stepped back and let him make his deal with the client. All I cared about was flying.

The day of the flight came and we left, bright and early, for Spokane. I’d already set up the mount as far as I could, tying it down with gaffer tape since it would be out of balance until a camera was on it. I’d put the door back on so we could maximize cruise speed to get to the client meeting site; the helicopter is limited to 100 knots with any door off. We got there on time and met at the FBO to come up with a plan. I had them top off the tanks with fuel and removed the door where the camera mount was. Charley set up his camera.

We wound up doing several flights. The first was a long one that started in Spokane, flew directly out to Dry Falls — which is about 2/3 of the way back to Wenatchee — circled that more times than I can count, and then headed down the smaller lakes to Ephrata, past Moses Lake, and over the Potholes Reservoir. On board were me (of course), Charley, and the video director (or producer?) who told Charley what shots to get. The mount took up a whole seat but I wouldn’t have taken a third passenger if I could; I have a strict policy regarding the number of people on board for photo flights and always limit it to three.

Dry Falls Photo Shoot
Here’s a closeup of my track, recorded automatically by ForeFlight, for the time we were in the Dry Falls area. What’s ironic here is that we flew around in a noisy helicopter for a good 15 minutes and likely bugged the hell out of people on the ground. A drone probably could have gotten the same footage without disturbing so many people. (Of course, it would have taken most of the day.) But because Dry Falls is a Washington State Park, drones are prohibited. Go figure, huh?

Dry Falls

After refueling at Moses Lake — we’d flown about 2-1/2 hours since leaving Spokane — we pretty much high-tailed it back to Spokane. Then we did two flights south past Cheney and east of Ritzville. That’s where the Drumheller Channels are. I’d never even heard of the place, but apparently it’s one of the best examples of the Channeled Scablands. One flight was with the same group on board; the other was with the geologist you see in the documentary. When the geologist was on board, the client’s own videographer flew with me, sitting beside me to shoot the geologist in the seat behind me as he spoke about what we were flying over. That’s probably also when they got footage of my helicopter’s panel and even me. Those two flights each took about a 1-1/2 hours with refueling in Spokane between each one.

After that, we were done. I dropped everyone off in Spokane, retrieved the door, and put it back on. Charley and I sped back to Wenatchee where we went our separate ways.

I think the whole gig was supposed to be just 5 hours, including travel time, but I flew (and billed for) more than 9. It was a very lucrative gig. But what was [almost] better was how much I saw and learned about the geology of the state. That’s one of the reasons I like doing aerial photo work; I get to see and learn a lot.

The Documentary

I have to admit that once my invoice was paid — which took a little effort since the money was coming from the UK — I didn’t give the project much thought. I didn’t even blog about it. That’s probably because last summer was very busy for me and I did a lot of cherry drying work. I even dried cherries later that day. I’d stopped blogging about my interesting flights, although I really don’t know why.

So imagine my surprise when a lawyer friend asked me yesterday in an email if he’d just seen my helicopter in a NOVA episode.

I went online and found the NOVA episode titled Killer Floods immediately. And although I rarely watch television during the day, I’m recovering from a cold and figured it was a good way to kill an hour. So I sat down, fired up the Roku with PBS, and watched it.

Let me start by saying I generally like NOVA documentaries. At least I used to. They’re filled with facts and good videography and leave you feeling better educated about topics than you were before you watched them. But I don’t know if it’s a general trend in documentary filmmaking or just a new NOVA style, but it seems to me that they’re trying too hard to sensationalize the topic or apply it to today’s world.

Two things immediately struck me about this one.

First, the name: Killer Floods. This particular documentary covered three flood events, all three of them were prehistoric. So although it’s likely that they killed something — plants? animals? — they didn’t have an impact on man at the time. In addition, their significance was not the fact that things were killed but more that the flooding changed the shape of the landscape by suddenly and violently eroding and washing away rock.

Second, the attempt to suggest that the three floods documented in the video have anything whatsoever to do with today’s flooding due to climate change. They managed to include footage from the flooding in Houston from Hurricane Harvey — a mere two months before air time! — which has absolutely nothing to do with these three prehistoric floods. Yet the narrator suggested that they might be related. I think that’s stretching it beyond reasonability.

But hey — I get it. They want people to watch so they come up with sensationalized names (see also Killer Hurricanes and Killer Volcanoes), and try to get people interested by pointing to recent events that they’re familiar with. After all, is the average person going to be interested in a documentary about how three prehistoric flood events changed the landscape in relatively remote areas of Central Washington State and Iceland or under the English Channel? I doubt it. NOVA is competing with reality TV, sitcoms, and sports. While I’m interested in just about any topic NOVA covers, most people aren’t. Sad but true.

That said, I thought the documentary was well written and produced, with plenty of good videography, interview clips, and narration. It walked viewers through the logical process of figuring out how each of the three landscape formations they were researching were actually made. (I already explained the one in Washington State; I’ll let you watch the documentary to learn about the other two.) The Washington one was a bit slow for me because I already knew the answer but I found the other two fascinating. I’ve been planning a trip to Iceland for late next summer and may extend it a few days to take in some of the sights shown in the documentary. And now I have a fresh desire to see the White Cliffs of Dover.

But what really tickled me was seeing my helicopter near the very beginning of the documentary, with the Flying M Air logo prominently displayed. Later, a shot shows my door with my name on it. And somewhere else near the beginning, you can see the helicopter’s controls and even a quick shot of me looking like a bit of a bum in my gray sweatshirt.

Those glimpses were enough to get my brother, who never picks up the phone, to give me a call yesterday evening. “I’m watching NOVA. Is that your helicopter?”

And that set off an hour-long conversation about all kinds of things. Heck, I talked more with him yesterday evening than I had all of last year. (Seriously: he just doesn’t like to talk on the phone.)

This obviously isn’t the first time I’ve been involved in a video production. I’ve been flying this helicopter since 2005 and have done countless video/photo shoots over the past 13 years. But I’m pretty sure this is the first one that has appeared on PBS or a highly respected documentary series like NOVA.

It’s about as “big time” as my little company will get — and that’s okay with me.

If you’re going to watch it, watch it soon. The website says it “expires” on December 7. If you’re really interested in flood-related geology, why not get the video? You can buy it on iTunes.

Look for me in the credits.

More about the Wind Machines

A few new videos.

Back in April 2015, I blogged about the wind machines commonly used for frost control in the Wenatchee Valley. Resembling tall fans, different versions of these machines can be found in agricultural areas throughout the west wherever frost — especially early spring frost — is an issue. Around here, they’re often in low areas subject to thermal inversions.

Wind Machine
The wind machines that were running this morning. That’s the Mission Ridge Ski resort in the background. Photo shot with my Mavic Pro.

The machines are fans that generate wind. The blades spin fast — faster than you might think watching the video below — to circulate the air. The fan heads rotate to constantly change the direction of the wind. The net result is that the air is circulated, bringing warm air from above down into the crops.

In the almond orchards of California, they use helicopters to do this. I think it’s because the orchards are so big that they simply can’t install and maintain as many wind machines as they need. The helicopters are likely a lot cheaper in the long run, especially when you have a few years in a row when they’re not needed. I’ve been on frost control contracts for the past five winters now and have yet to turn a rotor blade over an almond tree. (Global climate change?)

This winter was particularly long, setting the tree fruit back two to four weeks. The cherry trees are still blooming around here; last year, the cherries were already beginning to redden in the orchards closest to my home. Nighttime temperatures at my home have been in the low 40s. But in the orchards below me, pockets of colder air form. And this morning, they got cold enough to trigger the temperature-set auto start feature on the wind machines in the closest orchards.

I don’t know exactly when they started. I was up at 4:30, reading before getting out of bed, and I didn’t hear them. But by the time I made my coffee at 5 AM, I could hear them faintly through the walls and windows of my my home. I stepped out on the deck for a better look in the predawn light. The sound was louder and I could see two of the machines to the west spinning. My ears told me that one to the northeast, which I can only see from a handful of spots on my deck, was also spinning.

Here’s the zoomed in video I shot with my phone. When I shut up, you can hear the wind machines.

I did a Periscope — that’s a live Twitter video — of the wind machines. A handful of people tuned in and I answered questions as they came up. I was frustrated that I couldn’t zoom in. I signed off, used the video feature on my phone to capture a short zoomed-in clip, and posted it on Twitter. Then the sun rose and the light got good and I did another Periscope that was mostly to show off how beautiful the area was. The wind machines droned in the background of my voice as I described various things and answered questions.

I went inside, washed some pots from cheesemaking, and listened to the radio. I could hear the wind machines faintly through the walls and windows. I was sort of bummed out that I couldn’t give people a better view.

And then I remembered my Mavic Pro.

It took only two or three minutes to set it up. I launched it from my deck, got the video camera going, and sent it to the wind machines, stopping before it got so close that the wind could affect it. The light was beautiful and the image the Mavic sent back to me was clear. I hovered for a while to capture a good clip and then flew around a little, just taking in the view with the camera running. I stopped the video camera, took some stills, and then flew home for some more video of my home and the area around it.

Back inside, I made a fresh cup of coffee and spent a few minutes editing the video and setting it to music. It’s unfortunate that the Mavic doesn’t capture sound, but I understand why: it would be capturing its own buzzing sound, which isn’t pleasant. So music will have to do.

A side note here: I’ve been thinking a lot lately about how much I like living here. I realized — and I think I mentioned in one of those Periscope videos — that I like it here more than anywhere else I’ve lived. I’m not sure if it’s because of the place itself or the fact that I have a home with an amazing view built to exactly meet my needs or because after a stifling relationship that went on a lot longer than it should have I finally have the freedom to do what I want to do with my life and time.

Whatever the reason, I just want to remind readers that we all have just one life and it will eventually end. Don’t waste it stuck in a rut or in a place you’re not happy.
