Classic shot from the decayed lecture room at Beelitz. Shot a while ago, but always fun too go through old material and try new processing methods.
Some more documentary shots in my old blog post: Beelitz-Heilstätten
If you are inspired to do urban exploration after seeing my pictures, do so at your own risk. It can be dangerous and illegal and I'm not responsible for your decisions and actions. Don't steal things, break in or vandalize places.
