Hi guys, they're my shots, thanks for the comments.
"However, the comment that they must be High Dynamic Range processed (Lulu, 17:03) was a good one. The article gives the false impression that they were single long exposures... no mention of stacking, tone mapping, etc."
I provided the full tech details to the papers but they didn't print them.
Most of them consist of a HDR foreground image taken during twilight, then multiple startrail shots of around 1-2 minutes each, stacked using photoshop.
The first pic in the link in the 1st post, titled 'Nightshift', consisted of a HDR foreground and 720 x 60second exposures at f4.5 ISO800. Shot during the new moon and winter solstice for 12 hours of complete darkness & 180deg rotation. Shot with D7000 and 10-24, 15 hours shooting and 15 hours PP.
The second shot in that link 'Dead Tree Stars' was lit by a setting crescent moon, no HDR used in this one. 1 x 120 second shot for the foreground and 300x 60 second shots for the stars, f4 ISO400. D3100 and 10-24.
Reading the daily mail comments i got a good laugh from the 'scientific explanations' on why these shots are impossible.
Thanks.
Hakka.
