Lighting is an important part of our daily lives and it has become very important in modern life. Light has been used to create ambience, brighten our homes, control the time we spend awake and sleeping, and to create better working and living conditions. Lighting is divided into three main categories, which include natural, artificial, and decorative. Natural light sources include things such as sunlight, firelight, and moonlight. Artificial lighting sources include electric lighting, which includes both fluorescent and LED lights, as well as various other specific types of electric lights. Decorative lighting is the use of lights to produce an effect, such as a spotlight effect or an ambient effect. Lighting is used to create a pleasant environment and for visibility. A properly illuminated space or room can help improve mood and productivity, provide a sense of safety, control shadows, and improve visibility. Lighting can also be used as a design element to bring attention to particular areas, such as artwork or furniture. Lighting is also used in theatre and other stage settings to create a desired effect or mood. Lighting can also be used to create depth, contrast, and highlights on a stage. The use of specific lighting effects such as spotlights and dimmers can create a more dramatic and exciting performance. Lighting has become even more important with digital photography and video. Digital cameras rely heavily on the correct lighting to create the desired effects. Lighting helps to set the mood or tone of a scene and draw attention to certain things. Lighting can be used in a variety of ways to make our lives more comfortable and enjoyable. Whether its natural or artificial, decorative or functional, lighting can be a powerful tool that can help to improve our lives.
