I’ve used a Canon EOS 5D mark II with a Canon EF 16-35mm f/2.8L II, a TC-80N3 timer and a tripod.
The timelapse is taken in Tromsø, Norway, and it is captured from november 2009 to april 2010. Every single sequence in the timelapse is put togheter by 2-300 stillframes.
ISO-levels from 1000 to 1600 @ f/2.8 and exposure times from 3-6 seconds.
Every single stillframe is taken in Canons raw-format and edited in Adobe Photoshop Lightroom. I did some whitebalance and contrast-adjustments. I then exported the raw-files as JPEG in best quality and then imported in Adobe Aftereffects.
EXIF-data from one still-frame:
This is my aurora timelapse from 2009. Captured with Canon EOS 5D (mark I) and without a timer. I just pressed the shutter-bottom very many times.
Lens: Canon 28mm f/1.8 and 50mm f/1.4.
