So your telling me that your hobby has more legal right to exist than my right to reasonable privacy?
I'm not advocating a blanket ban but one of being able to opt out for future images.
For example, you take my photo as part of a street scene. As I have no idea of what you intend to do with that image, I respectively ask you to take no more images containing me. For all I know you may decide to manipulate the image then publish it on the web for the amusment of thousands. I wouldn't want that and whilst I dont have this right at this point in time, I believe I should have. The current laws only prohibit commercial photography which even there seems to be ignored.
If I don't want to be in your photography then why should I, in fact I believe you may even have the right to harrass me with your photography and I can't do anything about it. There has to be a reasonable limit and a right to privacy after the fact would seem to me to be acceptable.
