Dennis Andersons auroral epiphany arrived when he was 14. It was the night of April 1, 1975, and as he looked north from his home in Livingston, Mont., the sky exploded.
You had lots of rays and curtains and arcs and bands and lots of motion. It was almost a religious experience to be in the middle of that, to see the whole sky on fire, dancing, says Anderson, now 51 and living in Homer, Alaska.
Primed by that sense of wonder, Anderson now worships at the auroral altar night after long, frigid night, all though the Alaskan winter – with 10 or 12 cameras.
Anderson is one of a handful of photographers who make a living by catching the fleeting northern lights on film. And only on film, because only film can produce the high-resolution images he seeks. In a digital world, Anderson is strictly analog.
No batteries, no electronics, he says.
His prize camera is a hand-built giant he calls Franken-Cam. Each frame of film is about 2 1/2 inches by 3 1/2 inches, much bigger than the film used in conventional cameras. Its images have a resolution of 40 megapixels, about twice as many as the best digital camera.
He found the oversize lens he needed at an auction in Switzerland, a hunk of finely rounded surveyors glass rumored to have flown reconnaissance on French fighter jets and Israeli drones. At $1,500, he says, it was a bargain.
Andersons cameras dont have shutters, because he needs to manually control the long exposures he requires. Instead, he prepares to shoot by removing the lens cap and then holding the black-painted bottom of a coffee can in front of the aperture ... and waits. When a sky dance commences, he pulls back this black hat, and magic streams onto film.
Im lens-capping like your great-great-grandfather did 100 years ago, he says.
This is extreme aurora photography.
When his calling calls, Anderson packs the van and motors north, hour after hour, seeking some spot that hes previously seen and sketched and imagined as a pristine frame for a sky show.
Hell find it again, that copse with an opening aimed at the sawtoothed profile of Denali; or that one small lake backdropped by the spiky Wrangell Mountains; or that cabin up on stilts, unbroken snow sloping up to it, pines standing like silent sentinels.
The main thing is to put the time in, he says. Maybe it doesnt happen tonight or tomorrow. Maybe you get lucky and it happens next week. Sometimes you run out of time and you have to come back next year.
Triggered by a restless sun, auroras can appear year-round. But by May, the Alaskan days are long, the nights short. So Anderson works through the winter. Sometimes hes away from his wife and home for two or three weeks at a time.
Im basically camping, in survival mode, he says. I do have a place to sleep. I dont necessarily have a heat source. If Im out where the temperature is 30, 40, 50 below or more, I might want to stay closer to my vehicle and keep it running. If I shut it off for a few days, it might not want to start up again.
