"It was a big part for me to focus on the eyes because regardless of someone's situation in society they still have human eyes."
Mr Pharaoh gave each of his subjects money before asking their permission to be photographed, and spoke to them about their lives.
"It was pretty sad hearing their stories and seeing what they were doing.
"They were really friendly, I'm still pretty astounded that people lived like that. One lady especially I remember the most. She said she had 40 cats and the money would help feed her cats for a little bit."
Mr Pharaoh's work has been featured by the Daily Mail, Huffington Post and CNN and he has had offers for book, magazine and exhibition collaborations.
He hopes to print the series on to canvas and sell them, donating the profits to Red Cross.
