Visitors to Corby Glen Church are often surprised when they step through the porch door and are confronted with wallpaintings from the 1200s onwards.
Some of these are remarkably clear – look at the Christmas story on the upper walls of the main part of the nave, for example. Others seem blurry and indistinct.
But there’s a way to bring out more detail from those blurry blobs. Try pointing your smartphone camera at them and playing with the settings. What treasures can you find?
