NORTHERN LIGHTS
Based on my admittedly very limited experience, I
would have to say, in regard to Northern Lights, Aurora Borealis… well, La
Dee-Dah.
There is a ship wide announcement whenever Northern
Lights are observed. We were told that
things change fast. Intensities can
ramp-up or drop-off over just a couple minutes, so don’t give up right away.
Research back home in St. Pete indicated manual focus
(set at infinity), wide open aperture and exposures of 20-30 seconds (didn’t
give an ISO speed) – tripod required of course.
This seemed reasonable – until you factor in the tripod is on the deck
of a moving, ocean going vessel. I met a
local photographer who showed me a magnificent picture (he said) he took at 0.2
seconds with a fast f/1.4 lens. He said
he never exposes for more than 6 seconds.
So, the first night… well the actual first night I
didn’t see anything. Maybe those were
clouds, but… actually nothing. The bow,
where a dim show was supposed to be, was packed with unworthy gawkers, unlike
the photographically seriousness of myself.
The next night
then (tripod, manual focus set at ∞) I set the ISO (light sensitivity) to a
very high 6400. I set noise reduction to
maximum (requires about 10 seconds to process each image). I opened the aperture to the maximum for my
zoom lens, f/3.5, which is not bad for a zoom lens, but it is definitely not
f/1.4. I set the shutter to 30 seconds.
Shooty-shoot-shoot. Noth’n. Back in the darkroom (Corel Photopaint on my
laptop), I boosted color, brightness and contrast to maximum, and got someth’n.
Notice the big dipper
The next night the display was much more apparent, but
not what you see in pictures. There was
no structure visible (although some did pop out after post production
fiddling). As one watched the sky, one
could detect that the glow had changed, I would be hard pressed to call it
movement.
To become a documenter of the Northern Lights
Experience, I think you have to live around the Arctic circle (ugh) and work at
it some (or, at least, carry your camera at all times).
