An example of the vacuous type of item is his description of photographers working in black as opposed to other artistic approaches - this sounds deep and profound but he is fundamentally describing a working method, not a philosophy or meaning. Change the analogy and see if it holds - a sculptor working with stone, the basic element of our world evokes the more base or primitive feelings of his audience. Bullsh*t! "By contrast, the photographer inhabits the camera obscura, and he ultimately and always draws in the future viewers with him." Bullsh*t! Both are mediums of expression - the fact that the sculptor needs light to see is no more significant than the fact that I don't need a chisel to make a photograph. While his prose sounds impressive and admittedly somewhat poetic, it is not meaningful. However, I will take the time to read the book before deciding on its' value to me. If it has value to you, use it and care not what I think! I don't mean to discourage you, I mean to prod you into deeper introspection.
However, I would not get my hopes up too greatly for a thread like this - my experience is that people will discuss the precipitation rate of AgN03 in a metol solution for hours or the log of a exposure curve (I have no idea what these things mean, as much as I have tried) but will not read through a thread like this. There is a reason philosophy departments are generally small - not only can't you get a job with such a degree, it is intellectually harder to pursue than a number of other disciplines (I'm looking at you accounting!)
