Backlit Bison Breath and Starry Skyscapes: Teddy Roosevelt Day 2

Day 2 in North Dakota’s Teddy Roosevelt National Park started early…REALLY EARLY! Ryan and I crawled out of our cozy cocoons at 2:27am. Time to try for some Milky Way landscapes! It is always good to plan night shoots with a buddy, because if you are like me, it takes a lot of gumption to go out late at night by yourself. Unfortunately, we hadn’t scouted too well the day before, so it took some driving to find a good spot with foreground interest in the dark.

Normally you’d like to keep your star exposures to under 30 seconds…That way star motion is minimized. Over 30 seconds, you start to get “star trails,” short streaks of light showing the movement of the stars in the sky.

We had to get up in the wee hours of the morning since the moon did not set until after midnight….and any moon can wash out the stars and make the Milky Way much harder to see. I lit the hoodoos with my headlamp. Experiment with how much light painting you need to do to get pleasing results.

There is one easy thing that can really help your wildlife photography (that doesn’t involve expensive equipment!) and that is to GET IN THE FIELD EARLY! Dawn is the time when crepuscular critters may still be active and diurnal animals are also moving around. In summer, the mornings are cool and wildlife is more energized, much more so than during the heat of midday.

We found a heard of Bison backlit by the sun which was giving us gorgeous rim lighting on the coats of the Bison. Underexposing by several stops highlighted their breath on this chilly morning.

October is a great time to visit Teddy Roosevelt; Empty campgrounds, mild weather (25-60 degrees during our stay), golden grasses and abundant wildlife.

Mid day can be a slow time for wildlife photography, so search out scenics or macros where you can use this higher-angle sunlight to your advantage. I like how the tree trunks went black and the shaded hillside turned blue…not to mention the golden side lit grass.

You have to have a good reason to shoot into the sun. It works best when the sun is low on the horizon. I had to under expose the image by nearly 3 stops to get the pleasing rim light on the fur of this chunky Prairie Dog.

Aurora Borealis—Northern Lights Time Lapse

You don’t take Aurora Alerts lightly if you’re a photographer. So when Ryan forwarded the University of Alaska’s email that a major solar storm was happening, I was ready. That was three days ago and that night I peeked out the front door at the northern sky several times…but no green energy in the sky. Then last night (Friday, August 5th), after an email from another photographer, I checked the University of Alaska Fairbank’s website and the solar activity was EXTREME (+6). The maps showed that the aurora would be visible as far south as Minneapolis. This time I saw a faint glow in the north. It was 11:30pm.

My first stop was a little used public lake access spot, but a few flashlight-toting partyers nixed that. The next stop was perfect. The Spring Lake landing is right on a dirt road and with the lake on the north side, it is great for reflections. Green Frogs were “plunk”-ing and it was dead calm. Plus the moon had gone down. I set up my tripod right at the water’s edge. A few test shots confirmed that the lights were worth shooting. Digital sensors are much more sensitive to color than our eyes and the faint aurora was not so faint on the back of the camera.

Just then the lights started getting good…No time to attach my intervalometer, so I stood behind my camera and pushed the shutter button over 500 times…about every 7 or 8 seconds. The exposure I settled on was 4 seconds at f4 at ISO 4000…Not ideal as you really would want shorter exposures and shorter intervals so the time lapse would be smoother. But I don’t have a Nikon! (amazing High ISO capabilities). I shot in RAW so I could batch tweak images later. This meant “only” about 300 some images on an 8GB card. I did make one rookie mistake…I left the white balance on AUTO. This meant that each photo could have been a different white balance temperature. Fortunately this was easily remedied in a simple “Lift and Stamp” batch change in Aperture.

At one point, the lights were flaring, flowing, speeding across the sky in rippling ribbons of green…Almost directly overhead. The simple scientific explanation of this magical phenomenon is that solar storms (sun flares) throws highly charged particles towards the earth. Around the poles, they come into contact with oppositely charged particles and the energy from the collisions is light.

I got home at 1:45am but it was worth it.
