Hello to all,


I understand that in order to get sharp background objects one has to use f/11 - f/22 to get greater DOF. However, at night, with my kit lens, these settings seem too dark to get the shot. I had used fill in flash but the background still blur. I have with me Canon 50D with 18-200mm f3.5-5.6 IS kit lens.

Recently I went to Shanghai, China, trying to take sharp picture of my wife and a popular communication tower and historical buildings there at night, but I am not so happy with the pictures I'd got.
