One time the organization running a workshop DD (then age 4) attended allowed a local paper to come take pictures of all the kids without my knowledge or consent. They published a close-up shot of her along with her first and last name as well as the location of the building the workshop was being held, on the FRONT PAGE of our local paper. That's how I found out she was photographed. I was furious.
People make stupid decisions about the images they take of our children sometimes. That's why I always opt out of that sort of thing, and that's why I don't really like the idea of the people who spend time with DD thinking of her as one of "their" kids they can take pictures of for whatever they want. Those cameras probably go home with the teachers or assistants, and who knows who else has access to them in their households? It annoys me. Yes, cameras are everywhere nowadays, but schools have total unsupervised access to kids. It's not in "public" where being filmed is always a possibility that I can take into consideration.
Also, images of my daughter are special to me, as well as being images of HER. I don't like the idea of people using her image as a moneymaking tool, especially without her consent. School yearbook or specific class project destined for parents only are okay with me if they're okay with her, but I'd like a choice in the matter, thanks.
