Thanks for the compliment. I use a Nikon D50 w/ 18-70mm lens. For that shot, the lens was at 25mm, aperature was at F3.8 and exposure was 1/3 sec.
I actually had the camera set on Auto because I didn't have time to fiddle around with manual settings (plus, I'm not good enough to know what settings to use). The sunset was amazing that day, so I wanted to shoot as many shots as I could before the sky changed. The above picture was one of the last ones I took, after the sky had darkened. This one below shows how the sky had been a few minutes earlier. Unfortunately, the camera metered on the sky and, consequently, the WL itself is almost totally black.
