This exhibition looks at how photography has been used during criminal investigations.
It takes 11 case studies from the 1880s to the present day.
The first looks at when “metric” photography of crime scenes was first introduced.
It doesn’t just focus on individual murders, but looks at war crimes too.
The final case study is a reconstruction of a drone attack in Pakistan in 2012, which used digital and satellite technologies.
This exhibition contains images that some viewers might find disturbing.
