Once upon a time...

One reason I find Instagram useful: if you follow local photographers, you find places in your immediate area you didn't know about. Like the Burg Kriebstein (Castle Kriebstein). Just one hour by car from where I live and with the man-made rapids perfect for a long exposure.

 

Also used: Formatt Hitech circular polarizer and 8 stop Firecrest ND filter.
