For a while now, I've been attracted to black and white images involving long exposures of up to several minutes in length. If interested, check out Tony Sweet's website. He has wonderful images of which some are long exposures involving clouds and water. I really like the feel of these images. I find them very calming. I eventually bit the bullet and purchased a Hoya 77mm variable neutral density filter which according to the specifications would increase my exposures up to 9 stops. With this in mind, I was hoping that I could perform these long exposures any time of the day rather than at just dawn and dusk. So far I have been pleased with the results. The image of the dock was shot on a cloudy day at around noon. I used my Nikon D7200 and 70-200mm lens set at F22. Using the Long Exposure Calculator Version 2.0 app on my IPhone, the exposure was 4 minutes long. Although shot in color, I converted the image to black and white using Nik's Silver Effects Pro and made some additional adjustments. I'm looking forward to using this filter more in the future.
