I will quote My all-time favorite photographer...
"I am trying here to say something about the despised, the defeated, the alienated. About death and disaster, about the wounded, the crippled, the helpless, the rootless, the dislocated. About finality. About the last ditch." - Dorothea Lange
She also said...
"I would like to see photographers become responsible and photography realize its potential." - Dorothea Lange
Kudos to this person for a great photograph.
