10 stops...

Went off to Cambridge this morning to do many things... one of them was to try out the 10 stop ND filter I have acquired.  So it was another view of the Jerwood library that the filter turned into a 20 second exposure from 1/50 sec at f8.

Not really the best day for it but the river has been nicely smoothed out and the reflections enhanced.

For those that are interested this was a Hoya 77mm Pro ND 1000, and some step-down rings.
