I have a Powershot G16 that I'd like to use as my standard camera for its light weight. It takes amazing photos in the day, but I'm having some problems with handheld at night. I'm still a photography newb despite occasional forays over the years. I have this photo taken at f/1.8, 1/60 shutter and 2000 ISO:
It an OK picture, but the clock face is blurry and the image in general is not very sharp. Is this because of the wide aperture? I didn't specifically focus on the clock face, I believe I focused on one of the towers. What is needed to get this same image, but have the whole castle, including details like the clock face, sharp.
I don't believe this is a noise/ISO image and I know about post-processing techniques like photo stacking for enhanced focus. I just want to know if there is some setting that would make this adequately sharp. Should I go longer shutter and smaller aperture for greater depth-of-field?
