Do it enough and you'll get over it. Watch and see how people reacte when they see someone with a camera. 9 times out of 10 you'll se them posing for you.
One of my first assignments when i went to work for a newspaper was to go out and photograph an accident. i felt so stupid and felt like i was infringing upon these poor people. But then one of them walked right up to me and asked if i was with the media and was all smiling and asked if his picture was gonna be in the paper.
That camera of yours is an extension of you. It should empower you.
People do look at you like you are from outerspace if you are lying on the sidewalk trying to get that perfect shot of some building or you pull your car over onto the side of the road during rush hour traffic. Who cares! Are they ever gonna see you again? And if they do, they will remember you as the photographer that is willing to do what it takes to get that perfect shot. Might even land you a job or two!
Be proud of what you are doing. Act like you have confidence and people will really think you are a somebody and willprobably even ask you as much!
