Seeing is learned, someone born blind, and gets later the ability to see, initially will realize just and only light itself!
The real picture and the mental one that is produced are thus not identical for all viewers.
Further, the context in which one looks at a photograph will influence his mental perception. A photograph is always transformed into an illusion, a truth or beauty, but never in a new finding, in maximum it confirms something we already know. Accordingly, nothing is objective in photography and no photography shows the real truth.
Photography is a technical procedure, and a photograph is a produced image with the help of a camera.
Light, depending on the physical analysis is a wave or a particle - WHAT IS LIGHT?
Albert Einstein said: 'Light is born as energetic particle, lives as a wave and dies as absorbed energy.'
On that .. EACH PHOTOGRAPH IS AN EFFECTIVELY TRANSFORMED ENERGY!
