When you flip a light switch, a current of electricity passes through your light bulb. The filament in the light bulb then heats up, eventually producing a glow or the "light" we are used to seeing. Believe it or not, most light bulbs are more adept at producing heat than they are at producing light. Traditional incandescent bulbs waste far more energy than other sources of light simply because a light bulb produces so much heat. That is of course unless you use your light bulbs to heat a room!

Start with the task areas. These are best lit with bright, shadowless light. Fluorescent tubes are particularly well suited for this. You want to get the fixture close to the task area so as to get maximum light concentrated on the area you wish to work. In kitchens this would be counters, sinks, and tables. Spot lights and directional lights also provide task lighting in kitchens. For pantries or other closets, small Under Cabinet Lights provide good illumination. They can be mounted inside the closet above the door header to provide glare free lighting on the closet contents.

The most important property of light to the portrait photographer is the light's intensity or brightness. There are several ways of controlling the intensity of light striking the subject. In the studio, the power supply of modern strobes may be adjusted. The strobes may be positioned farther away from the subject. Outdoors, you may take advantage of cloud cover or the overhang of a tree or building, or even the time of day, to control the intensity of the incident light on the subject. These methods are effective for controlling the average light intensity of the composition. Many devices have been developed to control the relative intensities of light of specific areas within a composition.

You can get started with as little as one light, but make sure that you have some sort of reflector to provide fill light. Reflectors are available from professional camera shops, but a large piece of white foamboard or cardboard will do the trick as well. After your business gets going and you can afford more lighting, you can add a fill light, a hair light and some background lighting as well. You will need umbrellas or softboxes to go with your main and fill lights.

lighting lends a pleasant glow to your kitchen, thus giving a warm welcome to the people entering into the kitchen. It plays a major role in softening unwanted shadows, reducing kitchen room contrast and lighting vertical surfaces to give the space a brighter feel. It is generally observed that out of the four types of lighting, ambient is most often overlooked. In fact, the most dramatic and soft look you can achieve in a kitchen is by blending indirect lighting with other types of lighting. It is often created by hiding the light source from view where it bounces off a ceiling or a wall and produces a warm glow that adds enormous amounts of ambiance if done correctly.
