I didn't expect of the live view mode of my digial DSLR is necessary but I changed my view after I took this photo at Watson bay light house. It was an extreme dark on this cliff evening. What I could see was just the light house and used auto f to focus was impossible. Therefore I tried to use live view mode to help and enlarged toward the light house and manual adjusted the focus. A 5 mins exposure in small open aperture obtained a very sharp cliff view of Watsons bay and captured something which did not able to see from our eyes after 1 hour of sunset.
