Part 1: Timeline Reflection
Pinhole Camera (400Bc-1040AD)
The first capturing of imagery involved the design of a dark, lightless room with one side covered with large delicate sheet. The earliest mention of this device is by the Chinese philosopher Mo-Ti. A pin is used to pierce the sheet and create a small pinhole. On the outside where the hole was made place a lit candle. What happens now is that the light would travel from the candle through the pinhole and reflect an image of the candle on the opposite wall, but with the direction of light travelling the image would appear upside down.” The result was that an inverted image of the outside scene was cast on the opposite wall, which was usually whitened.” (Britannica, 1998).

Sadly because of the daylight the image soon became completely black, but before they were exposed to the light Niépce produced the first ever negative image, he named these images ‘retinas’. This only encouraged him to experiment more.
Heliography (1826)
In 1824 Niépce experimented with lithographic stones. he coated these stones with bitumen and attempted his permanent image experiment again. It took a tremendously long time with exposure to develop the image. it took several days, but his experiments finally paid off and Joseph Nicéphore Niépce obtained the first time-fixed, permanent image of a landscape. He named this process Heliography. Unfortunately, Niépce passed away shortly after and could not further develop this new discovery.

Only in 1839 did Daguerre explain the process step by step to the public. “The process revealed on that day seemed magical. Each daguerreotype is a remarkably detailed, one-of-a-kind photographic image on a highly polished, silver-plated sheet of copper, sensitized with iodine vapours, exposed in a large box camera, developed in mercury fumes, and stabilized (or fixed) with salt water or “hypo” (sodium thiosulfate).” (Daniel, 2004) This development was mostly used to create portraitures of people , as the process only took a few minutes compared to the previous several
