pmun,
There is quite a lot to say on this topic, so here goes in no particular order:
I personally do not find the images interesting or stimulating and the concept did not catalyse thoughts which were engaging. Herein lies the problem with conceptual art from where I am standing: it completely underestimates the intelligence of large swathes of the general public. If a person does not find conceptual art interesting it can be because it does not possess the necessary sophistication or nuances to generate a positive response. It does not have to mean that people have 'failed to engage' or 'failed to get it.' People are titillated by different things, so I accept that some may be stimulated by what you did.
I will use an analogy in literature - Sebatian Faulks. Which was his best book? Ask the general public and most would say Birdsong. Sure, its a superb book, but arguably more mainstream than what came later. I personally felt Human Traces was more powerful because of the exquisite subtlety and breadth of the issues touched upon and the manner in which Faulks did so. The issues themselves are profound to us all and actually very simple. Most of us have thought about them in varying depth, but Faulks was able to work his way through them in a way that (for me) was utterly compelling and forced me to think about every single one of them all over again. I did not have to battle against the current to do so. He led me on that particular journey and I simply could not have walked away without reaching my own end. Present the concept of that book to someone and it could be said that it had been done before, but my goodness it was done well. In this regard, I feel Human Traces leaned further towards the conceptual and Birdsong a little more towards the 'mainstream.'
To apply this analogy to your work: Your work did not compel and it did not force me to think about anything. It did not challenge me against my will or leave me thinking about things in a new light or altered sense of awareness. I will not use the word boring or get into the argument discussing what that means, but to me they were not the converse: 'interesting.'
I feel photography has to be able to stand up on its own two feet i.e. without a narrative or essay. Sure, they can add to the work and help ground it, but if the images lose everything in the absence of words, I am not sure that they can truly be alll they aspire to be. Photography is a visual medium, unless what you have presented here should be described as conceptual art that just happens to use photography as a partial contribution to the concept delivery.
