Another very interesting post  Andrew and food for thought. I now carry my camera every where with me but am aware of privacy issues as where I work in aged care we are not allowed to take or publish photos of residents on a non- work camera, and they have to have given signed permission even for that.I do feel though this is taking things a bit far.
I have only become photo savvy since having my point and shoot what a lot I have missed out on but at least I can make up for it now
