This week in Physics, Upper III have been investigating the history of the camera and photography as part of their topic on Light.

They looked at making and using their own pinhole cameras, which are based on the original ‘camera obscura’, which was historically used for artists tracing images.

They produced a projection of a filament lamp with their pinhole cameras and looked at how to focus the image and produce multiple images of the filament. They discovered that we actually see images upside down and that our brain ‘flips’ them the right way up. We also looked at how similar our eye and cameras are.
