To take good sharp photographs you need to have an adequate amount of light. Light is one of the most important ingredients in photography as it makes photography possible by reflecting off of the subject and entering your camera to expose the film inside. Lighting is just as important in digital photography too. Light that falls on a subject from a source is known as incident light. When this type of light strikes a surface, it changes direction; this is known as reflection.
Lighting conditions can basically be classified by the general type of light available. This can be direct lighting, diffuse lighting or ambient lighting. Each type of lighting means different approaches and techniques from the photographer. You may be taking shots in a studio or outdoors, using existing light, flashes, sidelight or backlight. The combinations and types of lighting are almost endless.
There are many accessories available to help you achieve the proper amount of light. These include flashes, meters, lights, filters and reflectors. These photography accessories can range in price from just a few dollars to a few thousand.
