My latest Flickr upload was shot some time back in Chicago. It depicts the Wrigley building (left of center) and the Chicago Tribune building (right of center) at night.
For night photography a tripod is almost a must, as exposure times will typically get longer, which will cause blurry images if the shot is taken with a handheld camera. While with some modern dslr camera’s it might be possible to push the ISO setting high enough to be able to capture these types of images at a fast enough shutter speed to allow for a handheld exposure, pushing the ISO to a high enough setting, will also introduce a certain degree of noise into the image. In this image a tripod was used and the camera was set at the lowest possible ISO setting (ISO 100), to get an image with the least amount of noise. The long exposures (this is an HDR) needed to capture this image also completely flattened the water in the Chicago River, making it silky smooth.
To get that beautiful blue sky I shot the image during the so called “blue hour”, which starts about 15 to 20 minutes after sunset and can last anywhere from 20 to 40 minutes and sometimes even longer. You can of course also get this same “blue hour” effect by shooting some time before dawn.
