Photography is a creative activity that renders imagination in a tangible form. It is a unique medium of self-expression. According to Wikipedia, “Photography is the process, activity and art of creating still or moving pictures by recording radiation on a radiation-sensitive medium, such as a photographic film, or an electronic sensor.” It requires aesthetic sense as well as technical expertise. Photography though mostly pursued as a hobby can be converted into a profitable profession.
With the boom in adverting industry and media, along with fashion boom, digital photography is becoming a lucrative profession and has great commercial value. It has become a significant part of print as well as electronic media. This field offers a lot of opportunities and scope for those who have an interest as well as aptitude needed for it.
Photography is the science, art, application and practice of creating durable images by recording light or other electromagnetic radiation, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film.
Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically “developed” into a visible image, either negative or positive depending on the purpose of the photographic material and the method of processing. A negative image on film is traditionally used to photographically create a positive image on a paper base, known as a print, either by using an enlarger or by contact printing.
