Lighting is one of the most important elements with regards to decoration and atmosphere. It can be divided into natural and artificial lighting.The use of light has been essential for mankind since prehistoric times to make use of the day time and night time hours. Natural lighting is the most conventional form of lighting, and it consists of sources that are obtained from the sun or the moon. These sources of light occur naturally and can be difficult to control in certain areas. Artificial lighting is a controlled use of light that is developed with technology. This can be used to create areas of focus, add brightness to a room and add ambiance. Both natural and artificial lighting are essential for creating beautiful and atmospheric environments, and they should be balanced carefully when decorating. Lighting can also be used as a form of safety precaution. For example, by placing strategic lighting on stairs and pathways, you make sure that they are easily visible and prevent unnecessary accidents from occurring. Furthermore, lighting can also be used for security, as well as convenience. With the proper placement of lights, it can serve as a deterrent against potential criminals, and make it easier for those walking about when it is dark. To sum up, lighting is an essential aspect of any living space, and when used properly, can create very effective and beautiful atmospheres.
