Photography: Introduction And Definition

The word photography is from two Greek words: phos (light) and grafis(writing), which means writing or drawing with light. Photography is the art of capturing images or taking pictures with a camera. Nowadays, the most common type of camera is a digital camera. Although some enthusiast still practices film camera photography.

The first experiments in photography came in the late eighteenth century. Cameras back then were large and heavy, and only professionals could use the cameras during those days. Cameras became accessible to the general public starting twentieth century. Later on, portable and instant cameras emerged. Camera technology further developed from black and white photo to color photo. Today, digital camera supersede the film camera because of the convenience of use and cost effectiveness.

Basic principle

All camera has a dark chamber, which is a rectangular box with a single opening through which light enters. The image is reflected on the surface opposite to the hole on a glass lens, which makes the captured image much sharper and clearer. Subsequently, the image is recorded on the photographic film and prepared for development. For digital cameras, the picture is captured by an image sensor then stored in a digital storage device such as SD card.

An art photographer is a person who gives artistic value to photography. He selects the theme and control lighting, framing, distance, angle, the arrangement of objects and other own expressive elements of photography.

Today, photography plays an important role as a means of capturing information and as an instrument of science and technology, as an art form and a popular hobby. With it, you can collect special moments and preserve it. Sciences such as astronomy, atomic physics, nuclear physics, quantum physics, quantum mechanics, etc, all use photography for their studies.

As for traditional art, photography assists in creating artistic works, although its role is technical. Their quality depends on the preparation, sensitivity, and creativity of the photographer, to give aesthetic value to its creation. Another role of photography is in journalism; it can highlight the events that the journalist wants to discuss. Topics such as political, social, observation of reality, issues, etc. are the common theme of documentary photography.
