Writing with light = PHOTOGRAPHY

Writing with the light, this is the meaning of photography and so the most common and ugly mistake in photography are related to the miss-knowledge of light. Even the blur images are often a consequence of this.
Most of the people that use a camera thinks that pushing the shutter button is enough to get a good picture. Well, thanks to technology, digital cameras and a pinch of luck, this is possible  but light can always surprise us, in a good or in a bad way.


To control light we must apply the correct balance between shutter speed - aperture - ISO

The perfect balance is related to type of photo we are trying to achieve. For example for sport/action/children/animals image we will give priority to the "shutter speed" and set the other two elements accordingly. Instead if we want to control the DOF (depth of field) then we will concentrate on the "aperture", more open is the aperture (the value is related to the lenses we use), for example f 3.5, less is the DOF and more is the light is coming in the camera, the clarity of the picture will be restricted to the point where we focus. If we want a to have a long table of people all perfectly clear the most simple way obtain a decent result is to focus just before the middle of the table, set the aperture to a close value, for example f 16 (don't take this value literally because light lead the choice), and then we need a suitable "shutter speed", why suitable? because more people is in the image highest is the risk that someone is moving. Then we check our camera exposimeter (if there is any) otherwise just follow the camera suggestions when you select the "aperture priority" setting.


ISO follows light, more light less ISO value needed, less light higher is the ISO value required.
