The Big Dipper was shot with a Canon 1000D (Digital Rebel XS) and an 18-55mm zoom lens at 20mm of focal length with a 2-minute exposure at ISO 1600 at f/3.5 on this barn-door tracker, driven by hand. Clouds obscure stars in the upper right corner of the frame. 作者: 几亩瓜 时间: 2011-8-23 23:32 标题: LOVE it [youtube]TmF31DmvlGk[/youtube] 作者: 几亩瓜 时间: 2011-9-10 12:01
