You go out with your camera and you see an interesting shot with people inside. However, it is impossible for you to take the shot without them noticing.
Do you ask for their permission first? Or do you just snap away?
I find that I am often too embarrassed to shoot people in the first place. How do you overcome that?
Thank you for the advice!
Just bring up your camera, focus and press the shutter button, thats it. If you can't bring yourself to do it, then forget about that genre of photography, there are others that might interest you.
A few methods to prevent being chase by people though,
1) aim your camera in a general direction, put to a smaller aperture, so that everything was sharp in your picture, and wait... anyone who walked into your frame and was captured by you is their own problem.
2) shoot your camera at whatever subject you want, then look away, or walked away. Don't care if they are happy or not.
3) talk to your subject and ask them for permission to shoot them.
4) for a start, go out in a group, so you will be more confident and when in a group, you will find more courage.
But do take care of yourself, try not to go to places to shoot streets when people there don't take these things too kindly... eg. go to the red light district in the evening or at night to shoot at you know what... you might get yourself killed pretty fast.
