These large-scale portraits provide a rare glimpse inside the Crisis Rough Sleepers’ Centre in London, which operates during Christmas each year. Cameras are usually banned from the Centre, but as a long-term volunteer Mark Burton was given permission to capture a series of portraits depicting guests and volunteers. The images portray the dignified and respectful relationships that develop at the Centre. This series of work also challenges perceptions of homelessness: the subjects removed identifying name badges or wristbands, often making it unclear who is the guest and who is the volunteer.
