How do I stop (some, any, all) people from taking pictures of me without my consent?

I already use a lot of magic and always do my protection spells before I leave the house. I have a couple of methods that have worked for me before, with varying degrees of success. But I need more. I need everyone to share their methods and ideas for how to keep people from taking pictures without my consent. I'll share one method I do, but we need to make this thread a collection of methods so we can decide which one to use. If everyone could tell me what they've done to protect themselves, we can all decide what is the best method. Thank you. Let's protect ourselves.
