Don said it: French new wave or The birth of the new avant garde.
Interesting what was in front of the four characters; men seemingly looking a bit ironically at the photographer, women looking at something else that prompted a curiously and almost comically surprised expression.
I think they were on a tour and listening intently to the guide, but I prefer to think something else has brought them all here, something that caught their attention and stopped them spontaneously and simultaneously. My favorite expression is the woman's.
i really dont know how you find these amazing combinations .. ppl beside geometric structures ..
altho i have found in insect photography .. that when you are switched on to that 'vibe' you will see things that you otherwise would have passed by and not noticed .. its like your eyes and brain become a compass leading you to what you seek .. almost without being aware that it is happening ..
maybe that is happening with you and your theme ..
love your black and white here .. and another great addition to your theme .. :)
