The decisive moment

this monochromatic image in the style of the decisive moment is cool, however i also like the reflection of the stranger in the gritty water.
the mood:
when i saw this picture, I had a lot of different feelings from it. for example i felt that the general feel to the image was quite depressing, however there was a slight feel of humour for me because the man is about to get soaking wet.
what is the medium of the work?
in this photo Henri Cartie Bresson used the style of photography called "the decisive moment" this is a style of photography that uses a method of waiting somewhere and waiting for someone to come into shot.
