The word Photography translates to ‘drawing with light’, but people practicing digital photography don’t really understand this while they capture an image, they measure light. Today, merely clicking a button captures an image. But earlier when photography was still being discovered, how to fix a photo permanently was the question. Many experiments have been conducted by artists and scientists in fixing the photo using different chemicals and natural sources worldwide in early 19th century. These processes in current digital era are considered as the alternative photography techniques.
