What are your methods as a historian working in a region with less written historical evidence? How do you work with images and photos?

What do we know about the past from images that we do not know from written material?

The colonial rulers took many photos; what stories do they tell compared to the photos that you find in people’s homes?

When you discuss the photos with people; how are the photos understood? What do we  know about the past from people's stories?

How do you use the photos? Can they be used in alternative ways of telling history?
