Photography
Photography (derived from the Greek photos- for "light" and -graphos for "drawing") is the art, science, and practice of creating durable images by recording light or other electromagnetic radiation, either chemically by means of a light-sensitive material such as photographic film, or electronically by means of an image sensor. 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. The result in an electronic image sensor is an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing.
The result in a 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.

Pada 1834, di Campinas, Brasil, Hercules Florence, seorang pelukis Perancis dan penemu, menulis dalam buku hariannya kata "photographie" untuk menggambarkan proses nya. Sejauh bisa dipastikan, itu adalah Sir John Herschel dalam kuliah sebelum Royal Society of London, pada 14 Maret 1839 yang membuat kata "fotografi" dikenal dunia. Namun dalam sebuah artikel yang diterbitkan pada tanggal 25 Februari tahun yang sama di sebuah surat kabar Jerman disebut Vossische Zeitung, Johann von Maedler, seorang astronom Berlin, telah menggunakan fotografi kata sudah.
Fotografi Kata berasal dari φωτός Yunani (Foto), genitive dari φῶς (phos), "cahaya" dan γραφή (graphé) "representasi dengan cara garis" atau "gambar", bersama-sama berarti "menggambar dengan cahaya".
