A decades-old photograph from Ghana's Deo Gratias studio, now in its centenary year, demands attention.

What emerges from the 50,000 images that still exist in the Deo Gratias archive is a record of a transforming society.

The Deo Gratias studio, still in the same place where it was founded just over 100 years ago, has stacks of old pictures and glass plates in its darkrooms, she says.

"Pictures speak tonnes, louder than what has been written," said Daniel Tetteh, a Ghanaian historian who volunteers with Deo Gratias as an archivist.

They believe their Deo Gratias photo studio is the oldest in West Africa.
