Fig. 20: This picture of circumpolar stars is made of 112 single exposures of 30 seconds each with an interval of 40 seconds. ISO was set to 3200 and colour temperatore to 3200K. From the lower part a timelapse on YouTubewas created. I realized afterwards that there is no movie format for portrait mode. — EXIF: Nikon D3; Δt=30 s; f=19 mm; f/4.0; ISO 3200; 2009-05-23 0:37:05
