While you may be able to see a scene perfectly well with your eyes, cameras do need a bit more light than our eyes in order to function properly. You do not need any fancy hand-held photography light meters for this step. The
meter in your camera will work perfectly well. Simply point your camera at your intended scene and press the shutter halfway down. However, be sure that you point your camera at the darkest part of the scene you are taking that you want to be visible in your image. If you take a meter reading from a brightly lit fountain, that beautiful oak tree behind it catching the light will be too dark to appreciate. Take your reading from the oak tree instead. Look at the readings it gives you. It may say that you need a flash, or if you have a SLR, you may see the metering bar showing you how much underexposed our image will be at your current settings.
