Finally got a chance to take a few shots with the B+W 10 stop ND filter, and it’s everything I hoped it would be. All of these shots were taken with the Canon 7d and 17-40mm f4 L lens. The above shot was taken in broad daylight where I was able to get a 30 second exposure at f22. Below are two shots taken later during the sunset the first is 56 seconds at f11 and the second is 240 seconds at f10.
