That was one of those lucky shots. It's a lava tube on the big island.
Click on the image above for the exif. I shot it with a Canon S330 (2 megpixel!) and, I was surprised to see, a 1 second exposure. I was on my honeymoon in Hawaii, so I know I didn't have a tripod. I must have balanced it on my knee or perhaps a hand railing. The tunnel is illuminated, evenly as it turns out, so this was not too hard. I've got quite a few lousy tunnel shots myself. They are deceptively difficult to photograph.
