Photography is the art, science, and craft of taking photographs by using light, either by using an optical lens on a camera, or chemically via a small light-sensitive substance like photographic film. When you take a photograph, you are using many different parts of your body to help create the image. Your eyes are the main source of light for the camera, as well as the natural movement of your arm, leg, and torso, the expression on your face, the subtle changes in light which are caused by things like water vapor or fog, and so forth. In addition, light is also transmitted through the skin and the hair which are part of your body and part of the environment which you are viewing.
Modern photography has produced photography cameras which are miniature computers in and of themselves. These have all of the functions of traditional point and shoot style cameras, though they are smaller, more waterproof, and more easily used for landscape photography than anything else. There are even some cameras which have the ability to analyze the light in the environment and automatically adjust the shutter speed and other controls to take the perfect photograph. These truly advanced types of photography cameras have truly advanced the art of photography.
Digital photography is still emerging, and even though more people purchase new digital cameras each year, there are still many more who are still satisfied with conventional photography. Landscape photography is one area in which digital photography is making a strong and noticeable impact. Many people are turning to digital photography in order to capture their love of the outdoors and to capture momentous events which may occur anywhere that there is light. Digital photography is truly a wonderful thing for any type of photographer.
