>>3614084this one seems a bit more obvious for no. 2 but it's really a reflection back on how holding a camera in public now often results in people generally being more aware of you and being polite
without a camera people are likely to walk in your way, bump into you, generally be a bit rude, but with a camera i've noticed people give me more space, even waiting out of frame for me to take my shot before walking in front of me
i shot this one in barcelona in one of the busiest areas in the city, yet around me there's nothing but space
