Some people are likely to think that you're police or MI5 doing surveillance. Or that you're planning a burglary, or intending to take pictures of children clandestinely. Or a million other reasons that people might dream up when they see a man with a camera in a car. You don't have to walk around a lot while doing street photography. Depending on where you live, there might be somewhere you can sit comfortably enough for a few hours, watching people coming and going, seeing what develops. And if your local area isn't good for that, a nearby big town or city is often ideal.it may feel kind of creepy taking photographs of strangers from a car?
If these are people you know, maybe they wouldn't mind if you hung around with a camera, looking for some candid shots. Once you've been there for a while, they're likely to forget about you.Gotta laugh thinking I'm with MI5 , as my first choice of location was some Asian supermarkets I used to frequent before lockdown, and many a time i wished i had a camera with me my knowledge of Arabic stood me in good stead when i visited, but i think give it a miss.
