I don't highly value your opinion of things until I see your competence demonstrated to me in a product.
Another point for consideration Marc: I presume you are selling your work.
In this context the ultimate judges of your work may very likely be complete aesthetic philistines who have no understanding of artistic significance never mind photography per se.
Furthermore, in the nature of commercial enterprise, one is guided in the direction of producing what sells, irrespective of what your opinion is of that work from an artistic and aesthetic viewpoint.
BTW, I have certainly not chosen to be insulted by your posts. This is an interesting debate and I would not want to close it down by being offended.
I can only reiterate that when one receives an opinion about one's work, from wherever it may come, surely one should interpret that opinion in the context of the work first. Very insightful comments can be forthcoming from people who are not photographers and understand nothing of the process. However, they have an eye for the artistic and the aesthetic.
It is not that difficult to judge the comment in this context.
Of course if individuals who have no idea of the process of photography are trying to inform one on the process then again it is not hard to pick the ignorant from the informed.
With regard to my image posts on LuLa, there are more apart from the post of that image of the Storey Bridge in Brisbane. However, as previously stated I am selective in what I post.
That particular image that you referred to was about three years in the conception and execution. I have shot the bridge many times but that evening gave me the light I had been looking for. The finished picture is a composite of twenty-four images. It prints beautifully to ten feet.
As far as I am concerned my photographic journey is definately still a work in progress. In this context I can learn much from others critiquing my work but also plenty from looking at the work of others. Being forced to commit ones thoughts to printed words and explicitly stating the strengths and weaknesses of an image certainly makes me think about my own work and measuring those same criteria to my work and also future projects.
