When shooting in low lighting conditions your camera will struggle to capture a correct exposure. You could pop up the flash, but this may not always help – it won’t illuminate distant objects, and it may not be permitted in certain locations. By setting your camera to a faster iso speed you can make it more sensitive to available light. this enables you to use a narrower aperture and a faster shutter speed in low light, but it can result in pictures that suffer from noise.
