A group gave 105 homeless people disposable cameras. These are the photos they took.

"Some people have had experience, and others have never picked up a camera before," said Paul Ryan, co-director of Cafe Art.

The program, Ryan explained, includes mentorship and training from professional volunteers at the Royal Photographic Society, including winners of the contest from previous years, many of whom are ultimately inducted into the society.

The goal of the challenge is to help participants gain the confidence to get back on the job market, search for housing, re-engage with their social circles, or even activate dormant skills.

"I really enjoyed it. And I started to get involved in my art again, which I'd left for years," a 2015 participant said in a video for the organization's Kickstarter campaign.

These are 11 of the top vote-getters from this year's contest:

1. Ella Sullivan — "Heart Bike Rack"

2. Alana Del Valle — "London Bus with Sculpture"

3. Beatrice — "Out of the Blue"

4. Laz Ozerden — "What Now?"

5. Leo Shaul — "The Coffee Roaster"

6. Christopher McTavish — "St. Paul's in Reflection"

7. Hugh Gary — "London Calling"

8. Keith Norris — "Watching Mannequin"

9. Siliana — "After the Rain"

10. Saffron Saidi — "Graffiti Area"

11. Jackie Cook — "Underground Exit"

Ryan, who has been developing the program for seven years, said that while there's no one-size-fits-all solution for individuals who are homeless, for some who are too used to being "knocked back," the experience of seeing their work on display or in print — and of success — can be invaluable.

"Everyone is helped in a different way, to get up to the next step in whatever way they need to."
