I just finished writing a short article on how to achieve and manipulate your shutter speeds on medium format panoramic cameras to get creative movement effects in water especially when you have limitations with fixed iso and only one stop increments in shutter speeds.
How the above shot was captured is outlined in the article. Shot on the Fuji GX617 | 90mm lens | Center Filter | F45 @ 1sec | Lee one stop soft grad.
