Einsten almost equate how the universe function with an equation...or did he not? Almost all human diseases can be tracked, diagnosed, treated and researched. They even mapped the genes of SARS in no time. Most physical phenomenona can be explain with physics, maths and higher sciences. Even serial killers can be profiled and studied. Human emotions can be explained somewhat. Art, most specifically photography, cannot yet be explained. There is no universal explanation for SUBJECTIVITY. No true determinants of what makes a good picture and what makes a not so good one. Photographers and critics are constantly evaluating others/own work based on their personal experience, attachments/detachments and emotions. In your opinion, will there ever be a day when we can put an EQUATION to photography? e,g Bad picture/Good picture = (composition x exposure x media used x subjects x tones x timing x camera used etc) in their various predetermined proportions and functions? SO in year 2050, a 6 year old kid would follow that equation and respectively produce a bad/good picture based on what variables he chooses in that equation? Or will art continually be sujective, which isn't a bad thing IMO I know, I have too much time. Thx for looking out. Happy shootout!
