Although I don't hold to the mantra that big cameras put people off, but that it's the way you point them at people that does that, a small camera makes me less self conscious about pointing it at people.
Of course when you know someone it's easy to point a camera at them. And they come to expect it!
Sometimes this works, sometimes it doesn't. It is good for me in that I have always been uptight about framing shots. The fluid way of shooting at arm's length does me good even if the pictures don't always come off.
One point of note is that sunny days make the market tricky to photograph with the stalls being shaded and the street brightly lit. Another reason for me preferring rainy days for shooting around towns!
A really useful outcome of my trip to market town was finding one way to make pictures about parking that I like. Which means I might get to make some more and the 'project' might get off the ground. I just need to stay loose.
