Thomas Ruff: working methods

From large-scale portraits of expressionless faces to digitally-coloured satellite images of Mars taken by NASA, Thomas Ruff's diverse body of work continually challenges the processes, techniques and concepts of photography. He frequently edits and manipulates photographic images made by others to reimagine their possibilities.

We travelled to Ruff's incredible studio in Düsseldorf, Germany, to meet the artist and find out more about his working methods, inspiration and how his art has evolved.
