2. Color temperature is an expression of the proportion of red to blue light that the light sources radiates. 

-As color temperature increases, the light becomes more bluish. Whereas when color temperature decreases, the light becomes progressively more reddish. 

6. The key light represents the function of the sun and provides the distinctive highlights and shadows in the scene. The fill light is used to create depth and dimension in the subject's face. It is often set to produce illumination about half as intense as the key light.

7. High side lighting-when the key light is placed higher than the subject to be photographed and to one side of the camera, somewhere between 30 and 45 degrees over from the camera axis and high enough so that the light can bed aimed down 45 degrees or steeper at a subject.

-Side light (Hatchet light)-splits the subject in half. 

-Side-rear light-the key light is placed to the side and somewhat behind the subject.

-Top light-the key light almost directly above the subject.

15. The safety precautions you observe when working with lights are never touch quartz bulbs, allow bulbs to cool before packing them away or setting them on objects, serious retinal damages can occur if bright lights are used closer than three feet, avoid shining bright lights directly into the lenses of older cameras, avoid plugging more than three lights into an electrical circuit, avoid 1,000-watt bulbs whenever possible, use only extension cords that are large enough to handle the job, and never discharge batteries completely or overcharge them.
