I don't usually like posting two shots of a series, but I simply couldn't choose between this one and www.flickr.com/photos/flatworldsedge/5206698402/in/photos.... This one offers the better composition and fewer distractions in the background, but it's a shame you can't see the expression on the waiter holding forth to the right.
This is another candid which owes its existence to Blackfoot Scout, my glamorous assistant, who posed in front of the waiters so I could shoot them candid over her shoulder. I've found setting the AF to the left or right most point helps - you can focus and get a light reading from the subject whilst pointing at your accomplice, so that when you swing the camera onto your subject you can shoot instantly rather than risk alerting them to your presence.
Hope everyone's having a great week.
