Took my GR + GW-3 wide to a high vantage point over a very busy highway (for those who know a bit about the Netherlands: the A7 across the Afsluitdijk). The GW-3 has a 62mm thread but it vignets heavily with filters so I use a 72mm filter on a step-up ring. An ND1000 brought down shutter-speeds to 6, 15 and 30 seconds on a 3 shot exposure bracket. Combining the 3 as well as the relatively long shutterspeeds got rid of the traffic entirely!

As a bonus, a HDR consisting of 3 exposures of the inside of the belvedere (the "Monument") which is located at the point where the builders of this huge dam closed the final gap:
