See, I couldn't disagree more strongly, Martin: in any artistic endeavour the theme is the starting point, the inspiration. The challenge comes in finding your own way through that. The problem with a lot of photographers (and painters, though less so sculptors, oddly) is that they can be too literal in an approach. In my case, I post the explanations for the same reason I post the multiple images, as a form of digital sketchbook to keep track of how my ideas have developed.
The theme should be a springboard, not a shackle.
