How it works
The Camera Obscura is powered by nothing but daylight. Part pinhole camera, part periscope. Look up in the viewing chamber and you’ll see a metal tube coming from the ceiling. The tube passes through the roof of the tower and into the open air. Outside, it’s covered by a protective hood with a tiny window in one side – this lets the daylight in. Once these light rays enter the tube, they hit a carefully-positioned mirror and beam downwards. Next, they pass through a set of three lenses – to focus a stunning image of Edinburgh on the table.
Did you know — Traditional pinhole cameras flip images upside down – our Camera Obscura is different. We flip the image twice – upside down, then back again. The lenses and mirror work together to create an exact replica of what’s outside.Close
