How to overcome the shame of being seen taking pictures outside?

If you are nervous every time you take pictures, it may be because you are not used to others taking pictures of you! Then you should try to overcome this psychological barrier, just like giving a speech on stage. If you treat the audience below as some radish and cabbage, you won't be nervous, and so will taking pictures. Just pretend that the cameraman doesn't exist, and you are putting on all kinds of expressions and actions.
