Make your own camera obscura and see shadows upside down! This activity is inspired by the camera obscura, a tool used for centuries by artists to help the accuracy and composition (layout) of their drawings. See a camera obscura and camera lucida on view at the Fitzwilliam Museum as part of our latest exhibition Hockney's Eye until 29 August 2022. The activity is suitable for children aged 6+ years.
