"Subject is merely a means to utilize these three elements of visual language."
~Bernice Loui.
Assertions re-imposed again. Not just Photographs, it applies to what is processed by the visual perception system and much more.
This applies to each and every photographic image made to this date. Definition of a ~Photograph~
Photo = Photon aka light as defined as a small section of the electro magnetic spectrum.
Graph = "A diagram showing the relation between variable quantities" in the case of a photographic image, this would involve varying densities of tone-contrast ratios and possibly color.
Given these basic definition of the noun Photography, this implies then defines graph made using light. By extension the given will be light, shape/form then composition which is the overall system which these elements exist on a 2D flat sheet.
Without light, there can be no visible image, without shape/form there will not be content for the mind-brain to translate into meaning which is directly related to emotions and memory. Know the human mind-brain is a remarkable pattern recognition system. This is why shape/form is so important and holds meaning to what is processed by the human visual system coupled with the mind-brain.
