judging from the style, which famous photographer do you think took this?

[Helena]

i need to source this image for an assignment, however i have no idea where it come from.
just by looking at the style (young asian girls with her grandfather in black and white living in a shanty) can you help me figure out who took it please?
if you know for sure and can source it for me even better.
thank you
