Brilliant shot. The expression on the guy far right is brilliantly captured.
Can just imagine what's going through his mind about the chap with the 'new fangled technology', and yet you'd expect his attention to be more concerned with the couple on the left!
Unfortunately I didn't make a series, yet. I love street photography, because the subjects are people and their everyday life. But it's not easy to face strangers with camera. Some of them behave unnaturally, some just like old North American Indians, who believed that by taking a picture of them, you can steal their soul.
About GR D I, It s great camera for B&W. I used to have one, but only for a while, because I wasn't happy with colour results and RAW writing speed. So I've decided to change it for GR D III. Now I take pictures in RAW mode all the time. I don't regret the change.
