Lighting is one of the most important and core areas of photography. Whether you use lighting correctly or no makes an impact on overall look of any photo. The end result or impact of any picture depends strongly on lighting. The kind of picture and use of lighting generally reflects the personality of the photographer. There are no right or wrong ways to use light, only certain given facts about various situations. For example, taking a direct picture of metal or glass is going to cause the resulting picture to have a reflection of the flash, or flare as it is called.
