..Flashes usually can be added stratigically to a scene, to enhance a subject's features or provide additional light to eliminate unwanted shadows. There are many types of lights, many we will not discuss in this section. Some that we will discuss are strobes, umbrella flash, and softboxes. All of these lights emitt short short spurts of very bright light. The gas filled bulbs that flashes typically use, provide a great deal of bright light, that can be used over and over many times. Another advantage to having a camera with a flash, is that no matter what type of light a scene has, you can give that scene a great deal more if it is neaded. This becomes useful when you are traversing through multiple scenes, such as a museum or indoor/outdoor mall.

Below are some pictures of several different flash units used in photography, but remember, there are many more we left out that you can find information about at your local photography store.
