Quality photo taking can be determined by the ISO settings used. ISO is simply the film’s speed. With the letters ISO on your digital cameras, it is possible to adjust the filming speeds. The ISO adjustment will determine your camera’s sensitivity to light. For instance, high sensitivity means a much grainier image. Camera speed settings may range from 64 to 1600. A low ISO number means a slow speed while a high ISO number means a higher speed. To get the best photo shots especially when outdoors in a sunny weather, an ISO measuring 100 or even 200 is good. At sundown in the evening, an ISO in the range of 400-800 is ideal. To get quality photos in the night or in cases of extreme low light, tuning to an ISO of 1600 is necessary or else you will get black photos or none at all.
However, it is important to note that most digital cameras take nice photos in a low ISO number. There should be just enough light to get in the sensor for good looking photos. You might not need a flash when shooting in theatres, museums or indoors in the evening but an ISO of 800 may just work well. This speed is also good for shooting moving objects or people in low light. You should learn to adjust your ISO settings always. To change the settings, you should press the ISO button. This can then be followed by either up down and left right buttons to alter the speed. However, note that a difference may occur in speed adjustments mode depending on the brands.
Remember that when using your digital cameras in automatic modes like landscape, portrait or sports, other basic settings like ISO, shutter speed, aperture and others are automatically done for you. You are free not to use these settings and pick your preferred ISO manually. By reducing the shutter speed, a camera has an ample time to gather the precise amount of needed light. However, a very slow speed produces blurry images. Increasing ISO increases the shutter speed and this will be helpful in shooting fast moving subjects clearly without blurs. Choosing the right ISO is a clever way of reducing noise in a camera and getting finer grains. You will note that an ISO of 100 is the normal setting for most commercial cameras. Others may go as low as 50 ISO but you will always have an option to adjust the required ISO for quality shots.
