 Taking good pictures in low light can be achieved in a number of ways. To maintain a proper exposure you may need to increase aperture, reduce shutter speed, use higher ISO or use a flash just as with a film camera. However with digital photography there are additional considerations.
Opening the aperture (lower F-numbers) opens the lens' internal blades that restrict light from entering the camera. By letting more light in, you can obtain a good exposure while keeping other camera settings the same. The two things to consider when using a reduced f-number, is the reduction of depth of field and that most lenses do not perform as well at their widest apertures.
Lowering shutter speed without making other adjustments can also help in getting the proper exposure. The rule of thumb is to set shutter time to no less than the focal length of your lens. So if you are using a 50mm lens, you should generally try to keep the shutter speed above 1/50 of a second. This will help prevent blurring the image due to camera shake |
