Finding great perspectives from which you can shoot is often the key to taking successful pictures. Plus, of course, the time of day and the light are essential. This is 13th century Conwy Castle in Conwy, Wales, and I photographed it at twilight -- my favorite time to take pictures of cities, skylines, and architecture. It's the mixture of the cobalt blue colors that occur just before dark and the golden artificial lights that make this time of day so special for photographers. I walked all over the area looking for a height that would put me above the rooftops for an unobstructed view. Conwy has a fortification wall around the town, and an ancient stone staircase to a walkway at the top of the wall gave me access to this wonderful view. My settings were 4 seconds, f/5.6, and 200 ISO. I used a 24-105mm zoom lens, and my white balance choice was 'daylight'.
