posts about time-lapse.
this weekend, i payed yellowknife a second visit. this time, during winter, with snow, ice, and freezing temperatures. and more aurora viewings.
here’s a first impression i got on the first day. it was taken at 14:20, and you can see that the sun was already pretty near to the horizon. the sunset is around 15:30, and goes down to 15:00 during winter’s shortest days. sunrise was around 9:30 the time i was there; it goes up to 10:00 during the shortest days.
i was staying in the narwal bed and breakfast, a small bed and breakfast located near the great slave lake, meaning i could just walk on the frozen lake and hopefully see some nice auroras during nighttime. here’s a nighttime impression, without an aurora but with clouds:
during the days, i often walked around and on the frame lake. lots of memories came up. it was often cloudy with breaks. here are some nice impressions:
finally, on the second and third night, the sky was mostly clear. and both nights featured auroras! the second night had a not very bright one, at least while i was outside, but the third and last night had some really great ones. here are a few impressions:
finally, here’s a video i recorded, consisting of 484 frames, each shot having an exposure time of one second. the movie is played back with six frames per second, i.e. you get a time lapse:
on our last night in yellowknife, we had the luck to see an aurora borealis. experiencing an aurora is something hard to describe. the following photos and videos just give a small glimpse of its wafting beauty.
for the more technically interested people, the camera settings i used for most photos are a shutter speed of 8 seconds, aperture of f/4.0 and iso sensitivity of 800. this was the first time where i was really happy that i have a remote for my camera’s shutter and a tripod. below you can view some videos, taken with these settings (hence, between two frames there are around 8 seconds delay). there are six frames per second, whence the videos are around 48 times faster as the real aurora was. each video comes as a flash player together with an avi download (the avi files contain essentially a sequence of jpeg files, so no fancy codec is required).
