Alatna Headwaters

 

In 2007, I had the pleasure of spending two weeks in Gates of the Arctic National Park & Preserve as the park’s Artist-in-Residence. During part of that trip, I camped at the headwaters of the Alatna River, one of several designated Wild and Scenic Rivers within the park.  During one evening hike, as I and my companion, National Park Ranger Tracy Pendergrast, were hiking back to our camp, I noticed the amazing golden light striking the mountains opposite of the headwaters from us.  It was about 11:00 p.m. and the light was really hitting that amazing quality it gets in late evening.  I set up this shot, and felt that it so well represented this part of the park – the open treeless landscape, the diversity of tiny plants covering the alpine slopes, the dramatic mountains of the Brooks Range, and the amazing Arctic light. This image was one of three framed prints I donated to the park as part of my artist residency.

Well, as it turns out, the staff at Gates of the Arctic felt that it really represented the park, too.  This image has been chosen to represent Gates of the Arctic at an exhibit that will be traveling around in Alaska in 2014.  Entitled “Voices of the Wilderness,” the exhibit will celebrate the 50th anniversary of passage of the Wilderness Act and highlight Alaska’s wild lands. I am pleased and honored to have my image selected for this important exhibit.  It has always been my goal and desire that my photography be used to highlight the value and importance of wilderness.  Given the magnitude and importance of the Wilderness Act, I am pleased to hear that this exhibit will be celebrating Alaska’s magnificent wild lands.  I hope that it is well viewed throughout the state, and it reminds people of the inherent value of wilderness.

At this time, the exhibition schedule is as follows:

Feb 2014: Sitka—Sitka National Historical Park

May 2014: Ketchikan—Tongass Historical Museum

June 2014: Juneau—The Canvas

July-September 2014:  Fairbanks—Morris Thompson Cultural Center

November 2014-February 2015:  Anchorage—Anchorage Museum

How to Chase and Shoot the Aurora Like a Pro

How to Chase and Shoot the Aurora Like a Pro

Alaskans tend to take advantage of their long days in the summer by getting out and hiking, biking, camping, and fishing.  We savor the opportunity to have six hours of sunlight to enjoy on a weekday even after the work day is done.  Farther north, the sun never even goes down.  But as winter comes, the light goes down sooner and the nights grow longer.  Temperatures drop, chills set in.  And while some types of activities go away, they are simply replaced by others that can be pursued in the winter.  Nordic skiing, snow shoeing, trapping and snow machining take over as popular outdoor activities.  And then, there is a small but growing (thanks to the prevalence of digital cameras) sliver of the population that pursues another activity: aurora borealis chasing.

There is a lot that goes into planning and preparing for a night out in the cold and dark seeking the perfect aurora photograph.  Some people head out more prepared than others.  I lean toward the prepared in order to not only be successful but to enjoy the experience.

Preparation

Unless you live north of the Arctic Circle, you can’t just head out on any clear night to photograph the aurora borealis.  There are certain conditions that produce strong auroras, strong enough to be seen farther south; and they are not always present.  So you need to know how to interpret the space weather as well as the Earth weather, and get a read on current conditions.

First, you can’t see the aurora if it’s cloudy where you live.  In Alaska, your best source of getting weather information is the NOAA Alaska Region website. You can get detailed regional forecasts and examine real time satellite imagery of cloud cover, including six-hour loops, in your area.  That way, if it is cloudy where you are, you can at least look for the holes in those clouds using satellite imagery.  Your best bet for nighttime imagery is to go with the “Thermal IR” or “Infrared” images.

Second, you need to know if the space conditions are going to produce an aurora in your area.  The first indicator is the strength of the forecast for that night.  The best forecast service I have seen yet is offered by NOAA, and you can subscribe to a variety of email alerts, but I recommend the 3-day forecast.  You can also view the 3-day forecast for geomagnetic activity directly on the NOAA Spaceweather Prediction Center website. It is updated at least twice times a day and has proven quite accurate since I started using it in 2013.  NOAA also has a 30-minute forecast.  Other short term forecasts include Soft Serve News.  I have not found the Geophysical Institute Aurora Forecast page to be accurate, as it is not updated regularly. You will want to look for what “KP Index” or “Planetary K-index” is predicted.  The higher the number, the further south the aurora will reach.  For example, a KP3 aurora can reach overhead Anchorage, while a KP7 aurora can reach overhead Seattle.  Your best bet for obtaining and understanding the data necessary to determine if there is going to be an aurora is to visit Spaceweather.com and SolarHam. Look for discussions on when a CME (Coronal Mass Ejection) is expected to hit the Earth’s magnetosphere, as well as the speed of the Solar wind (look for increasing winds, better than 500 km/sec) and a southerly Bz in the Interplanetary Magnetic Field.  The higher that Bz (south) number, the better. For the St. Patrick’s Day 2015 display, it was over 20. You can also see the current and anticipated KP Index.  Additionally, you can sign up for text alerts on Spaceweather, for a nominal monthly fee ($5).

Finally, in addition to the real time data on Spaceweather and NOAA POES Auroral Activity, sometimes it’s nice just to be able to look and see.  There are two aurora cams that are worthwhile to bookmark on your computer and smartphone. For Alaska, you can’t go wrong with Ronn Murray’s Alaska Aurora Cam, housed at Sirius Sled Dogs in Fairbanks. For Canada (even though I know of many Alaskans who follow it), keep an eye on the AuroraMAX aurora cam in Yellowknife.    For Facebook reports, join the Aurora Lovers and Aurora Borealis Notifications pages. I also follow the @AuroraMAX and @AuroraNotify Twitter feeds, which provide real time updates.

Ready for the Road

Most people who are experienced and prepared drivers in Alaska have a winter survival kit in their car.  I have one of those.  But I also have an extra set of gear in the back of my car to provide some additional comfort in my aurora hunting.  I have a bag that contains a MSR Whisper-Lite stove, a MSR bottle of white gas fuel, a Ziploc with snack bars, instant Starbucks coffee, hot chocolate, and plastic eating utensils.  There is a bag of Sailor Boy Pilot Bread and a container of creamy peanut butter to go with it.  I also have a small cook kit and a kettle for boiling water, and a travel mug for drinking hot liquids.  This bag, along with a few camping chairs and a -20 F sleeping bag, stay in my car at all times.

In my office, I keep a camera bag fully-loaded and ready to go for running out after the northern lights. Having the gear ready eliminates frustrating and stressful running about and panicking when you realize the aurora is going, and it avoids missing something important during that chaotic time. The bag contains my Nikon D800 and three lenses: Nikkor 14-24 f/2.8 AFS, Nikkor 24-70 f/2.8 AFS and the Nikkor 70-200 f/2.8 AFS VR.  I also stock an assortment of CF and SD cards, spare batters, lens cloths, Lee GND filters (in case there is a great aurora display over some artificial lighting, like the city or a cabin, or to balance exposure involving a reflection), battery charger, and AC inverter to plug into my car “cigarette lighter” outlet.  Sitting next to it is a one-gallon jug of water I take with so I will have something to boil to add to the coffee or hot chocolate packets.

Before heading out, you need to make sure you are dressed for the long haul.  From head to toe, you will not see me wearing cotton.  It has to be either synthetic or wool or fur, for the simple reason that cotton, when wet, takes longer to dry and does not retain heat as well.  For my head, I take a seal/beaver/otter hat handcrafted by an Inupiat artist, a thin hood layer, and a mask.  I wear two layers under my jacket, and a pair of thermals under a pair of snow pants.  For my hands, I prefer a thin liner glove underneath a set of fingerless gloves with a mitten flap.  On my feet, a pair of wool socks and a set of Baffin polar industrial boots.  Sometimes I wear moose hide Steger Mukluks of my Baffin boots, depending on how cold it is or how much snow depth there is, or if I anticipate possibly having to step through shallow water.

When to Go

Then there are certain times of the year that are best for chasing the aurora; you can’t effectively go aurora chasing when it is not dark.  (You could go in the daylight if you are a sucker for quixotic pursuits.)  I know, it seems crazy to mention, but a lot of people ask me when the best time of year is to see the aurora, or they ask if it has to be cold in order for the aurora to come out.  So, my answer is, the best time is when it is dark and in Alaska, that more likely than not means cold.  Sure, it starts getting dark enough to see them in August, and you can still see them in April, but most of the time during those months in between, it is cold outside.  Also, the aurora is most active around the fall and spring equinoxes – no one knows why, that’s just the way it is. That makes September-October and March-April the best times for viewing and photographing the aurora, although I have photographed some good displays in August and November.

Another consideration is the phase of the moon.  I rely on the U.S. Naval Observatory to check the phase of the moon and when it will rise and set at a particular location.  Unless you are planning on using silhouetted trees as your foreground, a new moon is not the best time to capture the aurora. A little bit of moonlight will bring some detail to the landscape and make your photo more interesting.  With a dim aurora, a full moon will provide too much light and overpower the aurora (but with a strong aurora, it doesn’t matter).

Where to Go

If the conditions are right and you have the gear ready, you need to decide where you are going to go for the evening.  I have scouted several locations within an hour to hour-and-a-half from Anchorage that have proven to be good locations.  What makes a good location? If you don’t want city lights in your photo, get out of the city and out to a location with an open view of the sky to the north.  Try to find a place with some foreground elements to add interest.  While sometimes the aurora can be awesome enough to stand on its own with a flat foreground that is generally not the case.  A great aurora photo also includes an interesting landscape.  Look for a location with some good foreground elements – water, trees, distinctive mountains, maybe some sort of structure (like an old bridge or building). Near Anchorage, good locations can be found along the Turnagain Arm and Knik River (although, be on the lookout for the pink glow of Palmer on your horizon).  The Matanuska Valley and Hatcher Pass offer excellent locations as you get farther away from Anchorage. Suitable landscapes with open skies can be found on the Parks Highway in the Broad Pass area just south of Cantwell.  The Interior regularly gets good views of the aurora on clear nights, from Fairbanks to Delta to Copper Center.  Farther north, great viewing can be found on the Dalton Highway near Wiseman and in Atigun Pass.

Taking the Photos

It may seem like a lot of settings at first, but once you get familiar with capturing the aurora, these settings will become second nature.

Lens selection and focus.  It is preferable to have a lens no slower than f/2.8 and as wide as 24mm.  Shooting at f/4.0 or slower will often produce too long of an exposure to get the brilliance you need for some of the less brilliant, but still lovely, displays, and it will create undesired star trails at exposures longer than 30 seconds, sometimes even 15 seconds depending on your focal length.  And having that wide focal length of 24mm or wider is key when you are trying to capture a phenomenon that encompasses the whole sky.  Disable your automatic focus and use manual focus; then set the focus point to near infinity.  If you place your focus point right at infinity, then you will get slightly-out of focus images.  Use your initial waiting time to take several test photos, moving slightly off infinity in each direction, and check the focus of the image (by zooming in on the stars while viewing in your LCD display) each time until you find the right setting.  If the moon is out and bright, I will actually turn on the auto focus, focus on the moon, and then turn it back to manual focus, locking in that setting.  You can also use Live View mode to zoom in on a focus point and manually focus on that.

Filters.  Remove any and all filters from your lens.  We all like to put UV filters or some other neutral, clear filter on our lenses to protect them from damage.  But any filter of any kind that is screwed onto a lens will create a distortion, represented by concentric circles, in dead center of your image.  Somehow, the light of the aurora bounces back and forth between the lens elements and the filter during long exposures to create the undesired effect. With that said, I have used graduated neutral density filters (square filters in a bracket attached to the lens) to darken a brightly lit foreground or to balance the exposure of the aurora with its reflection on a water surface.

Camera functioning.  The key to keeping your camera working is its batteries.  I always take at least three spare batteries with me when venturing out into the cold.  I keep them in a quart-sized Ziploc™ bag and tucked inside amidst the many layers I wear to keep myself warm.  As your battery power starts to wane, simply replace the cold battery with a warm one.  Also be mindful of condensation.  At extreme colds, your breath will fog up and frost the back of your camera, including the viewfinder and LCD display.  So, hold your breath when composing.  To prevent fogging and frosting of your lenses, either keep your camera and lens together in a camera bag when bringing back into your vehicle (and keep the bag away from a heat source), or simply remove your battery and leave everything outside.  If leaving your camera outside for extended periods of time, you may also want to cover your lens element to prevent frost buildup. One thing I will also do if I have my vehicle nearby is to run my camera directly on A/C power, running the power cable through an A/C inverter that is plugged into my “cigarette lighter” plug.

Settings.  With your aperture set at f/2.8 (or whatever is the widest opening on your lens), set your exposure mode to manual.  Then, set your exposure at 8 seconds and ISO at 1600.  This is a good starting point, but, depending on the intensity of the aurora and the brightness of the night sky (if the moon is out), you may need to adjust your shutter speed faster or slower and/or adjust your ISO up or down.  My most common settings are ISO 1600 at 6-10 seconds, but I have done it at ISO 400 at 2 seconds for a really bright aurora and ISO 3200 at 30 seconds for a really dim aurora.  If your exposures need to be longer than 30 seconds, then use a higher ISO before you set a longer exposure.  If your camera has the function, enable your High ISO Noise Reduction.  You may also want to enable your Long Exposure Noise Reduction.  Set your white balance to Auto. Finally, make sure you are shooting in RAW mode for the type of file you are creating.

Tripod.   Of course, the basic rules of long-term image stability govern: tripod, cable release, and using the mirror lock up feature.  One of the more challenging aspects of composition for an aurora shot is ensuring that your horizon is level.  This can be accomplished by using (a) a bubble level for your hot shoe, or (b) using the viewfinder grid in your camera (if you are lucky enough to have one; the newer Nikon cameras do).

Now you Wait

Now that you are suited up, geared up, have checked the latest data on what the geomagnetic activity is and have found a good location with clear skies, it’s time to wait.  And be patient.  And wait some more.  On a good activity night, you will not have to wait long, as the aurora can hit as early as dusk.  And if it is good and looks like it is going to remain busy all night, don’t stay in one location; move on to somewhere else to capture other images.  I like to diversify my shooting locations so that all of my aurora borealis photos do not all look the same.  Diversity is one way to make your aurora images stand out compared to others.  And just like any other landscape photography situation, it is key to vary compositions, lens focal lengths, and orientation (horizontal or vertical).  If you feel like you have captured “the shot” for the night, keep shooting and try new techniques and compositions.  When I can, I like to set up and capture images for creating a time lapse movie.  It’s best, though, to take along a second tripod and camera (or even a “rail” system) to capture the time lapse so you don’t have to worry about missing a good still capture.

A short night is typically about three hours.  On an October night in 2012 with a particularly spectacular display, I was out for eight hours, and could have stayed out more.  I felt, though, that by 4:30 a.m. I had captured a lot of really good images and could go to bed satisfied.  But even having great aurora borealis images to show for a night out in the cold cannot truly capture the thrill of just being out there and witnessing this amazing phenomenon.

Why I love Winters in Alaska

Thursday, November 7th, 2013

It has been a long, snow-less autumn. As a landscape photographer, I hate the shoulder seasons. After the snow melts in the spring but before things get green, it’s an ugly, brown, muddy mess. The departing winter has revealed six months-worth of trash lying around.  It’s not a pretty time.  The same goes for the transition from autumn to winter.  Once the leaves drop, it’s just a bunch of dead brown lying around.  Well, here in Anchorage, the leaves dropped over a month ago.  We’ve had a record-setting warm October, and finally the temperatures are starting to drop. Now, as crazy as it sounds, I am looking forward to the ice and the snow and the darkness.  Here’s why.   

  

Reason No. 1 – Golden light all day long

Most photographers will prefer to photograph at the margins of the day – early in the morning and late in the evening.  There is a good reason for this.  No, it’s not because we like to punish ourselves by getting up early (sunrise in Anchorage in the summer is about 4:40 a.m.).  The golden quality of light you can find at those times of day will make any landscape or wildlife subject sing – visually.  But in the summer and fall, that golden light dissipates fairly soon after sunrise, and does not come until late in the evening.  The higher the sun gets, the “cooler” the quality of the light, leading to less rich colors.  But in Alaska, in those parts where the sun does actually rise (Barrow experiences as many as 67 days of continuous darkness from November to January), the sun stays low on the horizon all day, leading to wonderful, golden light from sunup to sundown.  And you don’t have to get up early or stay up late to enjoy it. 

 

Reason No. 2 – the Aurora Borealis

A common misconception about the aurora borealis is that it only comes out when it is cold.  The fact that it is cold is purely coincidental.  It only gets dark enough to see the aurora in Alaska from about August through April, and that also happens to include the coldest months of the year.  But even as far south as Anchorage, you could easily spend twelve hours of the day out photographing the aurora because the skies are dark enough to see them.  See more in my Aurroa Borealis gallery.



Reason No. 3 – “I’m thinking, Pastels!” (Thank you, Regent Vitrini)

When the sun is low and the mountains (and landscape) are covered in snow, a magical thing happens, called “alpenglow.”  The result is a landscape aglow with a bold pink hue.  The presence of ice and the Earth’s shadow on the horizon before sunrise and after sunset add blue hues to the landscape.  The result is a luscious combination of pinks and blues that make for a wonderful tableau of color.

 

 

Reason No. 4 – Hoar Frost

Despite the extreme cold temperatures, there are many areas of Alaska that have open sources of water throughout the winter.  From moving water where streams and rivers collide to coastal zones, these open waters add moisture to the air, creating low-lying fog that clings to branches and plants.  The result is “hoar frost,” a thick, crystalline structure of delicate ice that turns any plant into a work of art. 

 

 

Reason No. 5 – Ice and Moving Water

It’s always interesting to combine movement with a static object.  In wintertime, you can have water be both the movement and the stable object.  Whether it is icicles clinging to logs over a flowing stream or tidal ice moving out with a retreating tide, there are plenty of opportunities to capture interesting compositions with movement. 

 

 

 

Reason No. 6 – Bohemian Waxwings

Usually in December when the air takes its first dive into deep cold, they come in waves to Anchorage.  Hundreds of feathered bodies swirling and moving together, Bohemian Waxwings move from tree to tree, usually picking at the frozen red berries of the mountain ash tree.  See more Bohemian Waxwings in my Birds gallery.

 

 

 

 

 

 

 

Reason No. 7 – Coastal Sunsets

I do not know what it is, but there is something very magical about sunsets in Alaska in the winter time.  It’s probably a combination of the all-day low light as well as the length of time it takes the sun to set.  But when you add in snow drifts, ice, alpenglow and all other variety of factors, winter sunsets, especially along the coastal areas, are simply awe-inspiring.

 

 

 

 

 

 

 

 

Reason No. 8 – Dog Mushing

It’s the official state sport and it is a load of fun to watch and photograph – a team of high-energy dogs doing what they were born to do; pull a sled.  There are a lot of opportunities to photograph dog mushing at various competition events throughout the year – Iditarod, Yukon Quest, Fur Rendezvous, and various regional races.  Some people will simply mush for recreation, like can often be found in Anchorage’s Far North Bicentennial Park area, particularly at the Tozier Track.  And with the magnificent landscapes, dog mushing subjects allow any photographer to capture an iconic Alaskan image. 

 

  

Reason No. 9 – Moonrises and Moonsets

The absolute best time to photograph a moonrise or moonset is when they correspond with sunsets or sunrises.  Why?  It is easier to get a balanced exposure – with detail in the landscape as well as the moon – when the moon is rising or setting while there is some light in the sky.  And as it turns out, there are some periods during the winter months – January is my favorite – when the moon is rising or setting at that perfect time. 

 

  

Reason No. 10 – Only the Dedicated are Out There

News flash – it gets cold in the winter in Alaska.  The record cold temperature in the United States was registered at Prospect Creek Camp in Alaska in 1971.  It was -80 degrees Fahrenheit.   The Prospect Creek Camp is located along the Trans-Alaska Pipeline in the Endicott Mountains of the Brooks Range, way north of the Arctic Circle.  While that temperature may be rare, certain parts of the Interior of Alaska will routinely see temperatures in the -50 to -60 degree range.  In Anchorage, we routinely get long snaps of below zero, and frequently see -20 degrees Fahrenheit.  Cold temperatures tend to thin the herd of photographers gathering at photo hot spots.  That is just fine with me, because cold is not a deterrent; it is to be embraced.  Photo magic happens in the cold, so long as I keep my spare batteries warm.
