Interesting. You are from my school of photography, playing with concepts and trying things!! I belive strongly in this approach to photography and think it is somthing that many of us do not do enough. I have just written a blog post called
Get out and shoot that kinda covers what you have done here.
As you know, the cost is nothing, no processing fees, just your own time and passion. The beauty of these shots, as well as being abstract is you can use them for boarders or backgrounds to other photographs. Thanks again for sharing the shots and a click of the camera is never wasted!!!!!
