Your photos exposures will be noticeably better.

Basically the photographer probably spot metered to get the brilliant contrast between AB and night sky.

There are too many discrepancies in these photos to be just spot metered. The stars show tracing and the clouds are showing movement. The more I look at these the more I think they are HDR composite images.

I went to Iceland in October. When I was there I saw the aurora and it was incredible - lucky enough to meet a photographer with a better camera than mine who could capture it and this is his flickr site - I was there for the one titled Seltjörn - amazing

Ahh HDR. Yeah probably. The tracing and movement have nothing to do with the spot metering. The long exposure would cause that.

Went looking through EXIF data on a few Aurora pics that look similar to the ones linked above. f2.8, shutter from 5 to 22 seconds and ISO 1600. That explains the HDR look.

An aperture that wide and an exposure that long will do it.

Enjoy

badass!

so on tv they always show them moving fast and whipping around - is that how it really is or does it move slow and they just time lapse it?

You're right. I'm sure it's completely lame and not worth you looking up into the sky to see it...

Some things just are never good enough for people.

Awwwe so pretty. I haven't seen an Aurora in like 10 years or something. I had a friend from the Yukon who was so blase about it. I still think it's magic.

They kind of shimmer in and out - not whipping around but they can appear and dissappear quickly - like bands of color passing over your head

A must-see time lapse.

That almost looks so fake it's hard to contextualize as something real.
