76: begin aurora sequence

The blog is going to be getting more attention these days. I just returned from Fairbanks, Alaska, where I spent a week watching the aurora and learning about the aurora. I took hundreds of photos and want to share at least dozens of those on the blog.



All of the following aurora photos were taken on Thursday, March 3, 2011, over a time span of 2 hours and 40 minutes. I was also taking pictures on the previous Monday and Tuesday nights, but the focus of those photos is lacking.

  1. Nice. I look forward to this series. Could you post exposure time, aperture, and ISO info for the aurora pics? I've always been curious what kind of parameters work well for auroral photography. Did you use a tripod?

  2. Can do!
    Exposure time: 6s
    Aperture: f/1.8
    ISO: 1000

    A tripod is a must. I'm not sure I have the best combo of parameters here. Now that I am reviewing the photos I think a little longer exposure time and a lower ISO would have been better to show how the eye perceives the brightness of the aurora (without over-brightening the sky/stars).
