In a world where is so many disinformation circulating around on the Internet and the media, it is a must to find a filter to distinguish the usable knowledge. We have to define a benchmark because the perceived and believed reality makes a difference. Nevertheless photography and visual perception are in a similar inseparable condition as well. The photographic medium is not only the visual representation of the reality, but the extension of the human vision. As every human perceive the world in a different way, the different photographic equipment does the same. So it is hard to talk about the reality and its definition because of its diversity. The only visual reliance is the color reference chart, which helps defining a photographic image due to its determined construction. My obsession is to find points of reference in the real world which can be used to define certainty.
