Photography is an art, the practice, and science of making fine, permanent images by capture light, either mechanically by way of an optical lens, or chemically through a light-sensitive substance like photographic film. Photography has been used since time immemorial to record human experience and give an impression of things that can not be seen with the eye. There are many different types of photography, including still life photography, portrait photography, fashion photography, landscape photography, wildlife photography, baby photography and others. The word “photography” derives from the Greek work “photos” (light) and “sophus” (craft). Photography is a technical science dedicated to capturing light and transforming it into a visible form.
Digital photography encompasses a wide range of processes, methods, and hardware in order to make digital photographs. There are two general types of digital photographs: a digital photo and a digital image. A digital photo is a representation of an object by digital code, which can then be transformed into a digital image using a computer. Digital photographs can be printed or copied as well as being stored on a computer.
Photography has existed since prehistoric times, when early man used stone or wooden statues to record events and record his observations. This technology was refined and improved by the ancients to the point where they could record images using lenses. Photography first became practical for general use during the Renaissance, and remained popular for the next four hundred years. The invention of the quartz camera made this technology even more affordable. Modern photography is associated primarily with the camera and printer, which have become integral elements of modern business, and thus, photography as a profession has become closely intertwined with business.
One area of photography that is enjoying a lot of popularity is landscape photography. Landscape photography covers the entire range from cityscapes to wildlife and everything in between. The key to landscape photography is understanding that the camera is merely a tool, and is not the focus of the image. It is up to the photographer to choose the right lens, select subjects, position the camera correctly and compose the photograph in such a way that it tells a story. There are different types of film, and different ways to use the camera, but the final output is still the same: a photograph.
Modern technology has enabled photographers to take their photography to a whole new level. One tool that is often utilized is a computer. By using a computer to analyze the light and color of the subject, a photographer can manipulate and optimize the picture with ease. Color correction software is available to the photographer which allows him to make corrections to the photograph and save it to the hard drive for future use. Exposure and flash adjustment can be done right on the camera by the click of a button, which greatly speeds up the process of taking pictures. Digital photography has come along way since the first crude camera was invented, and it is only going to get better.
Digital photography provides a wide range of opportunities for individuals who are looking to take on a career in photography. The different types of cameras allow even amateurs to produce high quality photographs. The tools provided with digital cameras also have the ability to adjust ISO speeds and aperture, allowing for a wider range of shots. There is a great deal of information available for those who are interested in photography, and these resources can be used to teach individuals all about the techniques and technical aspects of photography.
