Pinhole photography at Wimpole

Some time ago I bought a Holga pinhole lens.  Other than the odd shot, I haven't really used it.  So on Sunday I took a walk around the Wimpole estate park with my 7D mark II and the Holga pinhole.  I concentrated on the bare trees and the restored folly.  The resultant images I processed with Nik Silver Efex and Analog Efex to get some ancient looking grimy pictures.
