Leo Magers, 61.'First of all, for 30 years, I was used to having a very healthy income, having my own houses, doing what I wanted to do, and working. The most difficult thing is to have no money, and try to live on food stamps, and eat in dining halls, sleep with 200 men. And then for only four months at a time and then you have to pick up and move.'This series of portraits was shot at St Anthony's shelter in San Francisco, USA, in November 2014.
