if you don’t want people taking your picture, and they keep taking them anyway, there is a way to stop them!

all you need is a laser pointer. point the laser into the middle of the camera lens, and the picture will be destroyed! (you may have also broken the camera

Another way is to get an ultraviolet light. hold it up to your face and shine it at the lens. the picture will just show a shining light, which covers up your face. this method will not break the camera.

The last way, much like the second, is to attack ultraviolet LED lights to some glasses/sunglasses. turn them on before a picture is taken, and the cameraman will not be able to take anything that looks even remotely like your face. (I got the LED glasses idea from a video on YouTube by KipKay. check it out for instructions on how to build your glasses.)
