A candid picture is in my opinion the ultimate goal in street photography. By candid, one means taking a shot where the presence of the photographer does not alter the scene. Indeed, people have a tendency to modify their behavior when they find themselves being photographed. Some will smile, others will look away while most of the subjects will look at you in a puzzled way. Hopefully, there are some techniques to avoid this change of attitude, click here or on the picture to discover them.
