I was interviewed a couple of weeks back for part of the Photo Expert section in Digital SLR Photography Magazine which covers several different aspects of Night Photography.
The overall article’s well worth a read, pulling together different techniques and tips (of which my input is just one small part). The overall advice includes shooting star trails, urban light trails, moonlit landscapes and the night sky and is a great intro if you don’t want to give up the opportunity to get outdoors with the camera just because the evenings are now drawing in (which is exactly how I started). The magazine’s on sale at the moment – December 2011 issue.
If you’re interested in more details on the technique I use for getting the exposure just right for long exposure landscape shots, I’ve written up some information in a separate post on metering for low light landscapes.
