The Aldo Leopold Nature Center Blue Marble Campaign

I was recently hired by the exceptional team at the Aldo Leopold Nature Center to provide images for their Blue Marble Campaign. They've been hard at work installing the region’s first ever Elumenati Omnifocus Projection System in their Immersion Theater and needed both images of the theater system itself and interaction photos for promotion.

So what is an Elumenati Omnifocus Projection System exactly? I didn't know either until I made my first on-site visit. The center's promotional piece describes it as follows:

"This one-of-a kind panoramic astronomy and earth science theater software was developed by the Hayden Planetarium at the American Museum of Natural History and will take audiences on interactive, virtual journeys across vast scales of time and space, provoking questions regarding the nature of the universe and human’s role in protecting our fragile planet’s place in it. This will also be overlaid with cutting-edge infrared technology and customized content, creating an interactive immersive experience like nothing else!"

Picture a circular room wrapped by a screen. For perspective, consider that HD video is projected at a 16:9 aspect ratio. This particular system projects at a 40:9 aspect ratio. It virtually wraps around you when you stand in the theater. Multiple projectors are tucked into the ceiling and the content is controlled by a touchscreen podium at the back of the room. It's like something out of Star Trek...and it is seriously cool. It also happens to be an incredibly difficult scene to photograph.

There were two clear challenges with this shoot, the first was the room's dimensions, the second was the lighting. I wanted to show the entire room and briefly considered shooting a series of images and stitching them together but that would have made the room look too flat...too 2-dimensional. I opted to use a 15mm fisheye lens which gave me just enough coverage (within inches) to get the entire room in the frame. The distortion was severe, but I could correct for it when I processed the images. The second challenge was exposing the theater in such a way that both the projection on the screen and the hardware would be visible. This is of course impossible with a single shot, especially in a darkened room so I opted for a High Dynamic Range (HDR) sequence. This technique involves shooting multiple exposures of the same scene and "tone mapping" them together. I shot 5 images, underexposing 2 to capture the projected images on the screen, over exposing 2 to get the hardware and room detail, and finally, 1 that was properly exposed according to the light meter. Below is what they looked like right out of the camera. Note how the lens distorted the room and how, from an exposure standpoint, a single image simply wouldn't have worked. To get the projected image of the Earth, sun and stars meant the room and the projection equipment was far too dark. Conversely, to expose the scene in such a way as to illustrate the projectors and the room would result in a washed out image on the screen. By combining all of the below images I could bring out the shadowed floor, the projectors and the screen image.

The five unprocessed images used to create the final product. Note the drastic distortion before processing and the different exposures of each.

 I was hoping to recreate the feel of actually being in this room...the feeling of being on the bridge of a star ship looking out into space. After correcting for the optical distorion of the fish eye lens, tweaking the tone mapping, and doing quite a bit of cleaning, I was very happy with the result.

Final product: Projected image, podium, and ceiling hardware all exposed properly and entire room in the frame with lens distortion corrected for.

We also needed to create a compelling image that showed someone interacting with the theater. I knew just the photo I wanted...it was inspired not by any great artistic vision on my part, but rather by the system itself and how, just minutes after first seeing it in action, I could clearly picture my son Luc silhouetted by the earth, looking up at it in whimsically. And sure enough, once in the the room, that's precisely what he did.

For anyone who hasn't paid a visit to the Aldo Leopold Nature Center, you should consider it. The center boasts a number of impressive interactive displays as well as some great children's programs and beautiful outdoor grounds and trails. And if you go, don't forget to stop into the immersion theater. You'll be glad you did.

 

An Evening Along Lake Michigan

I don't blog very often about portrait sessions these days...likely because my photographic work has steered me elsewhere and I rarely do them. Yet when previous clients-turned friends recently contacted me and asked if I'd be willing to photograph them for their five year anniversary along Lake Michigan, I dusted off the portable studio strobes and got in my car.

Jonny Pearson and I shot Tony and Bridget's engagement and wedding photos five years ago. Besides being great people in general, these two are a photographer's dream: comfortable in front of a camera, patient, fun and up for anything.

They chose two locations for the shoot: Atwater Beach and the McKinley Marina break-wall, both along Milwaukee's Lake Michigan shoreline. I arrived early at Atwater Park to photograph the crooked docks that jut out into the lake. The docks are frustratingly (albeit it safely) fenced off from the public which meant getting a bit creative with my shooting position. By hanging my camera and tripod on top of the fence I could get a clear view. I fumbled around with my auto focus until it locked on the portion of the dock I wanted, then marked the fence with a Sharpie marker, removed the camera, locked the focal point and added a dark filter so I could I shoot a long exposure and smooth out the water surface before returning my camera to the position I'd marked. It took a few tries but I finally got it right.

Tony and Bridget arrived shortly after I'd photographed the old dock and as always, they were excited, ready to get to work and up for anything. And as if that weren't enough, they brought me a sample pack of beer from their new home in Nebraska.

The weather earlier that day had been miserable: high winds, overcast and showers. I'd almost called to cancel the shoot but by the time I was loading up for the trip to Milwaukee, things had started to make a change for the better. As we headed to the beach for our first images, we all knew it was going to be a beautiful night. We shot at Atwater for about an hour then headed to the break-wall and as the sun lowered, the sky became smeared with beautiful reddish-purple hues and the rising moon began to shine.

Capturing the moon behind the two required a couple of techniques. First, I positioned a remotely-triggered strobe unit close to them, just out of frame. Then I attached a long telephoto lens to my camera (which allowed me to show the moon as more than a dot in the sky) and hiked back to shoot them from quite a distance away. When the image was exposed correctly, I quickly shifted my focal point and exposure to the moon so I could bring back the detail of it during processing. At the beach, I created my own subtle sunlight using the same strobe unit positioned low and angled slightly upward, neatly hidden from view behind Bridget. While the image is meteorlogically incorrect (putting the sun low in the sky at dusk in the east) the effect was perfect and everyone was happy with the outcome.

Our final scene of the night (Bridget and Tony against the backdrop of the Milwaukee skyline) required a much shorter lens (50 mm) and some tricky climbing on the break-wall's rocks to get in position. We got what we needed and walked back to the parking lot as the boats returned to their safe harbor for the night.

I've broken photographic convention over the past decade or so. Most successful photographers will insist that you find your niche and stick to it, practicing until it's perfected. It's sound advice to be sure...and advice that I haven't followed. I shoot underwater, aerials, celestial scenes, High Dynamic Range, and even portraits. I haven't perfected any of them but there's one thing I can say without doubt: I've learned from all of them. And techniques from each discipline have found their way into others. Portrait lighting for example has been a great benefit for me when lighting my subjects underwater. There's always something to take away from any kind of shoot.

A warm thank you to Bridget and Tony for trusting me to capture their evening together. I hope your trip back to Milwaukee was a memorable one and I look forward to working with you again.

The Lake Superior Collection

When classifying water bodies, there seems to be something of a taxonomic gap. The three largest (lakes, seas, and oceans) are categorized by (among other things) what surrounds them: a lake is surrounded completely by land, a sea is surrounded by land as well but may connect to another body of water, and an ocean is effectively "without boundaries." It all makes sense.

That is of course until you stand along the shore of Lake Superior. That's when you feel like the classification system missed something, A water body after all, that has a surface area greater then Vermont, Massachusetts, Rhode Island, and New Hampshire combined, that can swallow 700-foot ships, and that can create its own weather system shouldn't share space on the same list as Madison's Lake Monona. I suppose that's where the term "Great Lakes" comes in, but anyone who has spent time on or along her knows this particular water body is something special- something unique.

Last week, when the moon's phase, the weather, the Milky Way's location and my family's schedule all somehow managed to cooperate, I made the run north to the Canadian border at Grand Portage, Minnesota. I've been interested in creating a Lake Superior Collection for a while now, adding to some of my previous images of the lakeshore. There were several things I wanted to photograph, but above all I wanted to capture the Milky Way behind a small, offshore rock islet named Hollow Rock. I arrived at Grand Portage around 4:00 pm and with another seven hours until I could try for the Milky Way, I refilled my coffee mug and set off to my first location: The Pigeon River's High Falls.

The falls are located in Grand Portage State Park. True to every Minnesota state park I've visited, it's superbly maintained and getting to the falls was easily done by following a paved trail and climbing a wooden staircase to an observation deck. The problem as a photographer however is that anyplace that's easy for you to get to is easy for everyone to get to. I waited patiently (outwardly anyway) as park visitors jockeyed for selfie positions on the deck. With a dark filter covering my lens, I needed between 7 and 10 seconds to expose the shot. This requires using a tripod that has to remain absolutely still...a feat not easily accomplished with a crowd bouncing around. I finally got a break and took this shot, pleased that my angle showcased the bright rainbow in the river water's mist. By 7:00 I'd made it to my small cabin at Hollow Rock, gotten more coffee and began scouting a location to set up for the night's shooting.

According to all of my planning tools (which these days are all on my iPhone and include apps for moon phases, direction and time of sunsets, Milky Way locations, etc.) the Milky Way would be visible in the southern sky and work its way west. I set up facing roughly south so I could capture Hollow Rock in the foreground. Because I wanted to be able to see the islet and not just its silhouette, I would need to "light paint" it, that is to say add light for a short time during the long exposures I'd need to bring out the Milky Way. Because exposing stars and the Milky Way requires setting your camera and lens to be very sensitive to light, I knew light painting would be tricky and overexposing the island, smearing light onto the water, and getting bright "hot spots" would all be likely. To combat this, I put together a very unattractive but highly effective light paintbrush built onsite from an Ikelite underwater flashlight, a Fong strobe diffuser, and a piece of cardboard I'd scrounged from the garbage to deflect the light away from the water's surface...all bound by duct tape.

By 10:00 I'd set up along the rocky shore and by 10:45 the Milky Way was traveling across the sky, just as promised. By opening my 24mm lens all the way up to f/1.4 and exposing for around 15 seconds, I could clearly see the Milky Way in my view screen. With my shutter trigger in my mouth, I began painting the island with my makeshift light paintbrush. It took a couple tries but I finally got it and even in my camera's screen I knew I'd done it right. It's rare (for me anyway) to have a picture I took so closely match the image I'd imagined prior to shooting it but that's exactly what happened last week. Planning, patience, and a roll of duct tape paid off beautifully.

I couldn't sleep Monday night. I was exhausted but couldn't get my brain to quiet down. I had a short time to shoot (three days total which included travel time) and I wanted to process the images I'd just taken--something I won't do until I'm at my desktop computer. I also knew that once beyond 10:00 am or so the next morning, the light would be too hard to capture all the scenes I'd have liked to. I found myself in a place I'd been countless times before: The first day of a shooting trip and already frantic for more time. I looked through images, pored through maps to figure out my next location and finally fell asleep about an hour before the alarm woke me at 4:45. I groggily crawled out of bed, grabbed my camera and got some early morning images of Hollow Rock, then headed out in search of more subjects.

Clear skies and bright sun can be a photographer's worst enemy. The light is hard...too much contrast, too many shadows, and skies that are far from compelling. Rather than wasting time shooting scenes better attempted in the dawn or dusk hours, I decided to take to the sky with my drone and get some shoreline footage. I spent several hours flying through rock lined bays and thoroughly enjoying myself. I've yet to sort through the footage but will do so soon and post it when I do.

I hoped to find someplace shaded to shoot and came across yet another Minnesota State Park that looked promising: Cascade River. I hadn't really driven this far to photograph waterfalls, but I had some time to kill before the storm front (and hopefully some interesting clouds) made its way to the area. This time I shot from a bridge and faced none of the crowds I had at High Falls. I set up, grabbed a few images and continued on.

I photographed a couple more waterfalls and tried to figure if there was a safe, legal way to launch my drone and shoot the Split Rock Lighthouse from the air but there wasn't. I was beginning to get a bit discouraged (and more than a little fatigued), when the clouds started rolling in from the west. I was close to Split Rock River and a set of old pilings I'd wanted to photograph so I hit the trail again for the short walk to the water, now diffused by cloud cover.

By around 5:00 I'd run out of steam and needed to get to Duluth for the evening so I packed up my gear and started the drive. Along the way, I drove past Two Harbors, where a few years back I got an image that will find its way into this collection, taken at sunrise off a rocky ledge behind the Superior Shores resort.

After oversleeping the next morning (and by oversleeping I mean I crawled out of bed at 5:30) I found myself at a bit of a loss as to where to go. I needed to be home that evening and had just missed a spectacular sunrise (which, when you only have three days to shoot and you're along the lake shore is almost unbearable). I decided to make the short drive to one of my favorite places in the world: Bayfield, Wisconsin and the Apostle Islands. I knew by the time I got there the light wouldn't be very good, but there would be a hot breakfast waiting at the Egg Toss Cafe, and I could wander around the docks a bit.

Like Two Harbors, Bayfield (and the neighboring Red Cliff) are places that I've gotten images that will be included in the Lake Superior Collection. Two of my favorites follow: The first is Bayfield Marina at sunrise, the second is Little Sand Bay at dusk. I've had the pleasure of hanging both of these images on people's walls and hope to do so again.

Provided you have the time and a little luck, there are virtually endless scenes to photograph along Lake Superior's shorelines and islands. I've barely scratched the surface. If anyone has ideas for me, please leave me a comment or contact me directly. Fine art prints on a variety of mediums are available here.

The Florida Keys 2016

This has been quite a year filled with incredibly rewarding projects including corporate art sales, architecture shoots, advertising work, a refurbished website (take a look around if you haven't already), an upcoming online art store, and the biggest (physically speaking) piece I've ever created: A 26-foot long display for the University of Wisconsin.

And I haven't written a single blog about any of it.

I'll blame this on Facebook, an environment that I hesitantly joined last year. It gave me an easy way to showcase my work and it's been useful but I need to get back to this blog for a number of reasons. And what better way than a piece on one of my favorite places: The Florida Keys.

Those of you who live in the Keys understand its rich history: Hurricanes, Hemingway, and one of the most "daring" road building projects ever attempted.

Then and Now: The long Key Bridge connecting Long Key and Conch Key. The bridge originally shouldered the Overseas Railroad from 1907 to 1935 before being used for highway traffic. The current bridge is used for foot traffic and the new US 1 runs pa…

I could have spent the entire week with my lens focused on the region's historic elements, but I was staying in the upper keys for another reason: The Key Largo National Marine Sanctuary.  Established in 1975, the sanctuary provides protection to the continent’s only coral reef. Later, in 1989, the Florida Keys National Marine Sanctuary and Protection Act was passed, designating 2800 square nautical miles of coastal waters from the Dry Tortugas all the way to the Everglades as a marine Sanctuary. Strict regulations, put in place to preserve this fragile underwater environment, prohibit the collecting or damaging of any coral. I've been coming here since the early 1990s when I brought groups from our dive shop to explore the reefs aboard the Sea Dwellers boat. We've all gotten a lot older, as evidenced not only by the sheer quantity of reading glasses laying around the Sea Dwellers shop, but by my need to borrow a pair. Nonetheless, the waters surrounding the island chain have changed little and once on the boat, it felt as it always had.

For those of us in the Midwest who endure snow removal, ice covered roads, and the unwanted guest of late who goes by the rather daunting name of "Polar Vortex", booking a trip to southern Florida in the late summer (when the weather here is beautiful) seems a bit counter intuitive. If your purpose is to shoot underwater however, it really is a great time. The water is warm, seas are generally calmer, and visibility is good. And on this particular trip, the sea life was not only present, it was extremely cooperative.

With a new underwater camera housing, rebuilt strobes,  and a different camera than I typically shoot with (I could write an entire blog titled "camera's I've flooded and housings I've ruined"...) I headed beneath the waves at Molasses Reef. Diving without a group provided me with perhaps the single greatest photographic luxury: Time. I scoped things out a bit away from the others then I simply waited. It's a strategy that paid off.

When the Reef Sharks came in, they came in fast. Accompanied by their entourage of Jacks, they swam around for me for a bit, seemingly indifferent to my presence or the bright flash of my strobes. I photographed them for nearly twenty minutes before working my way back to the boat. With 15 minutes before needing to surface, I bumped into another pair of animals that typically are skittish around divers: Reef Squid. Again, I sat with them for a few minutes until they acclimated to sharing space with me before I started shooting. Capturing highly reflective, translucent animals isn't easy and I needed to make a lot of strobe adjustments (both position and power) to get it right. But I had time and that made all the difference. I wanted two particular images: The first was an underexposed, dark background where I relied on my strobe light to bring out the colors of the squid. The second was a photo that showed the animal's translucent qualities.

And of course there's always a turtle (well, almost always a turtle) and the next day I spent most of an entire dive with this one. I'm not sure how I got so lucky on this trip, but when I came across him, I got the same feeling I'd gotten with the sharks and the squid: He couldn't have cared less that I was swimming with him. Perfect...let's get a few pictures shall we? I followed him for 45 minutes as he looked for sponges to eat, firing off my camera the entire way.

Anyone who has been diving on a healthy reef knows that while these animals are all spectacular and sought after photographically, the entire environment is beautiful. I've become very particular about what I shoot but if you could see just beyond these images you'd be treated to a magical landscape of "riotous color" (to borrow a quote from famous author and avid scuba diver Michael Crichton) that is bustling with life. Even when you don't find the shots you're looking for, simply being on the reef can feel like a privilege.

Warm thanks to Rob Haff and the Sea Dwellers gang for always making me feel so at home when I visit. Key Largo is a very special place to me and I look forward to returning.

Super Blood Moon 2015

Last Sunday night was a rarity: Not because the moon was full; Not because its path trended close to Earth, making it appear nearly 15% larger than normal; Not because an eclipse bent the sun's light around the Earth, turning the moon a deep magenta color. No...the real rarity Sunday night was that while I was out shooting all of this, the clouds (which seem to delight in plaguing me every time I try to photograph a celestial scene) were nowhere to be found. They must not have gotten the memo instructing them to flow in and obscure my view whenever I aim a camera towards the sky.

The Setup: Canon 1DX for stills, Canon 5D MKII for time lapse.

The Setup: Canon 1DX for stills, Canon 5D MKII for time lapse.

Shooting a picture of the moon itself isn't a particularly difficult endeavor. A long (telephoto) lens is a must, otherwise the moon, which looks so spectacular to the naked eye, will appear as a mere dot of light in the sky...a disappointing result experienced by the droves of people I saw shooting it with their smart phones. A tripod is a good idea as well, helping to steady the camera and avoid blurring the image from camera shake. Finally if at all possible, manually setting the camera's exposure is the surest path to a moon image with detail. Cameras set to automatic exposure average everything in the frame which will often cause a boost in exposure level to compensate for the dark sky, in turn blowing out the moon to little more than a bright white orb.

I had two goals last Sunday: (1) Get a picture of the moon in context, that is to say, an image that gives it a sense of location (my mind of course went right to the capital building), and (2) Try for a time lapse piece showing the transition from full moon, to eclipsed to red.

It became apparent pretty quickly that a time lapse piece wasn't going to work out. Using a long lens meant limited space in the frame and during the time it took for the eclipse to go through all of its phases, it simply moved too far....way too far. I started my sequence with the moon in the lower left corner of my frame at 8:11 pm. By 8:38 pm, it had already moved through the entire frame and exited the other side. I knew it was a bust, so I concentrated on still images. I'd set up at the top of Wisconsin Avenue where it meets Langdon at the newly rebuilt Edgewater Hotel. A crowd of people had gathered to watch the phenomenon and the atmosphere was positively festive. I talked to others, showed them the images on my view screen, coached a young photography student through exposing the scene correctly, and handed out business cards to those who were anxious to see the finished product. The night had the feel of Mallory Square during a Key West sunset.

As the moon began to shift to a reddish orange color, I had an all too familiar realization: I was in the wrong spot to get the shot I needed. The telephoto lens created a very narrow scene and to get the capital and the moon in the same shot wasn't going to work from my position. I quickly gathered up the cameras, raced to my car and miraculously found a parking spot right next to the capital square. From here I could get the moon as well as the "Golden Lady" statue atop the capital dome. To accomplish this, I needed to aim my camera upwards, focused on the moon. The resulting composition gave the illusion of the moon being much lower in the sky than it actually was.

The shot had its own set of challenges, exposure in particular. A proper exposure for the moon was far different than that needed to get the illuminated white capital dome. This was easily solved by shooting a High Dynamic Range (HDR) image. I set my camera to shoot 9 images: four over-exposed, four under-exposed, and one that the camera's light meter assumed was right on. By doing this, I could tone map them together, bringing out the darker moon and avoiding a dome that was blown out. The result is the image above.

This was an exciting shoot for one very simple reason: It won't happen again until 2033. The next time I have a shot at this, my three year old son Luc will be 21 and I will be comfortably into my sixties. It makes you think....If you're a photographer, get out and shoot these things and if you're not, make the time to watch it. I must have talked to a dozen people that night who remembered what they were doing when they saw the last blood moon. It's a conversation I hope to be having during the next one in eighteen years.

What an amazing night.

 

 

 

 

2015 Perseid Meteor Shower Time Lapse

It's always something when shooting time lapse...always.

As I sat at my computer yesterday, everything looked to be converging beautifully: The forecast called for clear skies, the nearly new moon wouldn't rise until after 4:00 the following morning, assuring a dark shooting environment and most exciting of all, the Earth was passing through the orbital path of the Swift-Tuttle Comet, whose debris field would pummel the atmosphere later that night resulting in the Perseid meteor shower. I even had a rural shoot location along the shore of Crystal Lake near Wautoma, Wisconsin, far away from the light polluted skies above Madison. I spent much of the day preparing for what I felt certain would be the best clip I'd ever shot. I'd sit down to write this entry, then triumphantly upload my dazzling video of the cosmic light show I'd so brilliantly captured and top it off with some compelling Carl Sagan quote about stardust or the solar system.

But this is time lapse, and there's always something. There was indeed a convergence last night...of unwelcome clouds and some rather poor choices on my part. 

When I arrived at Crystal Lake I was met by our friend Ann who, together with the Davis and Riley families own the lakeside home where I would be shooting. The house is perched high above the lake on a wooded, sandy terrace. Down slope a pier extends out into the lake, which is where I decided to set up my camera. The problem with my choice was that the only unobstructed view of the sky I could get was east - southeast. The meteor shower was going to be "easy to see," the meteorologists had assured viewers earlier that day, by simply "looking to the northern sky."  It would seem that I had overlooked a pretty important requirement for this shoot: I wasn't facing the right way. Nonetheless, with a wide 24mm lens I could aim high and was confident that I'd capture enough of the northeastern sky to get some comets. And that's precisely what I should have done.

Two things happened around 9:30 last night: The linear form of the Milky Way began to materialize in the southern sky, and I learned that my 3 year-old's knack for being easily distracted and veering off task must come from me. It was the Milky Way after all, far too tempting to resist. The comets would surely venture into the southern sky. I decided (based on absolutely no astronomy knowledge or training) that they would. I promptly rotated my tripod head directly to the south...180 degrees from where I should have been shooting.

With everything logistically in place (or out of place depending on how you looked at it) I had to turn my attention to the technical challenges of the shoot. I shot with a Canon 24mm f/1.4L II lens, which I opened to f/1.6. Before beginning to shoot, I pressed the depth of field button then rotated the lens, detaching it. By doing this, it became a fixed aperture lens, insuring that I would avoid flicker- the distracting staccato effect that can turn a great time lapse clip into a mediocre one, or worse. There was an additional problem to contend with during a shoot this long:  Dew drops condensing on the glass. Last year I shot for three hours in the Nicolet National Forest only to discover that the lens had completely fogged over early in the sequence. Not this time. Enter battery powered fans, Gaffer’s tape, and hand warmers.

The setup: Battery powered fan to repel insects and hand warmers wrapped in neoprene to warm the lens and avoid dew condensation.

The setup: Battery powered fan to repel insects and hand warmers wrapped in neoprene to warm the lens and avoid dew condensation.

Dew is basically water that condenses on objects that are cooler than the Dew Point temperature. Tonight the Dew Point was around 60 degrees which meant if the temperature dropped close to that (cooling my lens glass in the process) water would form on it. I needed to keep my glass warm. There are a number of ways to do this, but I chose the cheapest (and arguably least attractive) method: I used Gaffer’s tape to attach a series of hand warmers to the outside of the lens then wrapped the whole concoction in a piece of neoprene I’d cut from one of my old wetsuits. These warmers are cheap and last up to 7 hours. I also set up a battery powered fan below my camera-a method that has proven effective for keeping insects away from the lens.

With fan whirling, the settings locked in, and viewfinder covered, I began the sequence. I shot at f/1.6, ISO 3200, with a 20 second exposure time. Because I wanted to use some of the images as stills, I followed the “500 Rule” of star photography: Take 500 and divide it by the focal length of the lens I was using, in this case, 24mm. I divided 500 by 24 which gets me a number just shy of 21. If my shutter was open for more than 21 seconds, the stars would begin showing up as trails, an effect I didn't want. I used a 30 second interval:  2 shots per minute; 120 shots per hour. Since the result of this whole endeavor will be an HD video clip played back at approximately 30 frames per second, every hour I shoot, I’ll get about 4 seconds of video. That's a lot of time and planning to get 20-25 second clip.

Once the camera was going, there was no point in staying with it so I wandered around the property a bit, shooting a few stills with another camera, sat with Ann for a long overdue catch-up session, and even grabbed a 45 minute nap. I periodically walked back to the lake edge to make sure the camera was still firing and I began to notice a disturbing lack of stars in the southern sky. I knew that my camera would pick up stars that I couldn't see, but the northern sky (which I should have been shooting in the first place) was positively crowded with them, brilliantly lit and remarkably defined. The southern sky on the other hand, had an odd yellowish tint that meant something I dreaded: a low bank of clouds had streamed in and was reflecting the tungsten light from the cabin porch lights below, masking the stars in the process. I had chosen exactly the wrong direction to shoot, a sickening realization four hours into the shot on a sleepless night.

But this is time lapse, and there's always something...and sometimes it's interesting. The clouds, which I'd feared would completely obscure the stars and the Milky Way, only did so partially as they raced past, adding a level of depth to the piece. And even hidden behind the clouds, the Great Rift of the Milky Way (the dark seam of dust clouds that run its length) was visible. A few stray meteors did in fact find their way into my scene. I made a lot of mistakes last night, but I still ended up liking the sequence. The next moonless Perseid meteor shower will be in August 2018, so I have plenty of time to make a plan and convince myself to stick to it.
