Photography is defined as a science, art, application and practice of creating lasting images through a process of recording light or electromagnetic radiations. Photography is a discipline used in different branches of science, manufacturing and business. Nevertheless, it is directly used for art, film and video recordings, hobby, recreational purposes and mass communication.
Photography is the result of a combination of different techniques and has evolved over the time. Firstly, the concepts of optics, camera obscura and pinhole camera have been outlined in China. Afterwards, all these notions have been tested by Greeks, Byzantines and Arabs. Nevertheless, the first image captured with the camera obscura dates back to 1800.
Originally, all the photographs were printed in black and white and they have been dominant for decades due to their lower cost and ‘classic’ status. The first permanent colour photograph was taken in 1861 by using the three-colour separation principle.
Nowadays, with the digital development, digital cameras have become popular among people. These tools use an electronic image sensor to record the image which consists of a set of electronic data.
The term photograph relates to an image created by light which falls on a photosensitive surface (e.g. photographic film or electronic magnetic sensor). Photographs are taken by using a camera, which utilises lenses to focus the scene and reproduce the image which is perceptible by the human eyes.
The term photograph dates back to 1839 and means ‘drawing with light’.
