Partial reflection

It was the annual Ogden Awards night at Lancaster University last night and we got our first view of the new department buildings. The lighting conditions gave us the perfect example of a type of partial reflection. You can see the inside of the building. It must be being lit by light from the outside which is going through the glass, hitting the room and reflecting back to us. Then light from the outside also reflects back off the outside of the glass showing us the world behind us.
