Steps...

The Socttish Mining Museum (back of house). An incredible, and v dangerous, place to take photos. Donned the hard hat and safety boots to go behind the scenes passed the Dangerous Building Do Not Enter signs - worryingly.
Took hundreds of photos.

These steps are near the main shaft and do not look like they have been used since the mine closed - thick with coal dust and the room was almost completely dark this was 30s exposure

Well I have to do something with my 3 days off per week...
