, I wrote about how to make a 360° panoramic time-lapse film
using an egg timer. For the photo above, I didn't want to go with twelve 30° views, but instead combine all 360 images into one panorama. This meant to cut from every photo a tiny narrow centre slice (only 22 pixel wide in fact), which is equivalent to one degree field-of-view. These were then all combined into one large image. If you look carefully, you can make out the stripes.
On the next day, the weather was much nicer, and I repeated the egg-timer photography. However, due to the GoPro camera's fully automagic exposure settings, and the high variability in lighting caused by fast moving clouds and the bright Sun, it was not possible to make a nice pan-lapse out of these photos, and as you can see, the stripiness is much more pronounced in this image, even though the blue sky is very nice of course.
By the way, the strange black boxes in these photos are part of the Kilpisjärvi Atmospheric Imaging Receiver Array (KAIRA
). The mountain directly under the Sun in the second photo is famous Saana.
In due time I will write about how these were done in detail, in case you want to try yourself.
