Robert Doisneau was a french street photographer.
He started working as a photographer from the 30s.
I find his photos quirky and inspiring because they depict human nature in an unexpected and quaint way.
Here are some of the images I found off google (please note I do not own anything - I'm just sharing it for your pleasure ;] ):
His most famous picture was
Le baiser de l'hôtel de ville (The Kiss)
He also had a google doodle dedicated to him last year.
I'm not a photography expert, but these are very artful. What do you think of his work?
