I’ve put the full set of this event as a slideshow on Flickr. It was a really good event and deserves a slideshow. I really had to push the limits of my camera for the shots by the Chinese Arch. It was dark. ISO1600, 1/30th second shutter and f/4 at 10mm. The problem was the I needed a long exposure to bring out the background, but then that just created blur. So these have been boosted in Lightroom by nearly 2 stops and of course that means noise.
