Light, vision and reality

Thanks to the introduction of digital picture post production for fine tuning the images is a common and well known practice: it is worth to mention that also in traditional photo techniques dark room post production work was part of the process to optimize pictures frequently “making the difference” for both color and b&w pictures.

A common question related to an image is related to the extent it represents reality. A unique answer to this curiosity  does not exist and cannot exist. For sure a printed picture, regardless to the type and technology used, traditional or digital, is one of the many realities the shot can represent.

An image is always the result of what the author has “seen and wanted to transmit” being the combination of light, author’s vision and the set of technical aspects applied which contribute to define how the author present his work and each single viewer sees it.

It is evident that the shot reality never correspond to the image we see, it is an author’s choice to limit or expand the post production activities, what always count in any case is only the result and the image capability of developing emotions and admiration for what is represented and for the author’s capabilities.

What could be said about b&w pictures? We are aware that they never represent the reality we see and nobody would question on how we see, in colours, and how reality is shown, in gray scale.

Finally we must not forget the single viewer vision adaptability, due to brain activity, different for each individual, which support our sight. The most easily detectable are the compensation of subjects in direct light or in shadow area and the vision in natural or artificial light of colours, while cameras capabilities, despite high technology, are always related to physics laws and always include defects: been aware of this it is easily understood that reality differs from the image in any case despite post production work, applied technology and hardware used.
