A really interesting article. Street lights in the UK (and I guess most of the world) are now switching over to LED. From an aesthetic and environmental (and tax payer) perspective, I have to say I like the new look. In the article you linked to, the second wide angle picture of LA at night shows a much greater contrast, and the night sky is a lot darker! There's nothing to be done to stop it happening (if you don't like it), but perhaps getting those clear night-sky pics will now be a little easier. Thanks for posting the link.
