Three main elements that we first need to know with our digital cameras the ISO, SHUTTER SPEED and the APERTURE these are the elements that affects the exposure of your photograph The first thing that i want to introduce to you is the Shutter Speed. Shutter--is a small plastic sheet that opens and closes to allow light onto the film or prevent light from reaching the film or image sensor.Shutter Speed ---amount of time that a shutter is open. In Digital Photography Shutter Speed is the length of time your image sensor sees or exposed to the scene you are attempting to capture. The basic information we need to know about shutter speed is that the longer the time it is open then the brighter your photo will be because of the amount of light that entered the image sensor. Shutter speed is measured in seconds – or in most cases fractions of seconds. The larger the denominator the faster the shutter speed.
