I tried to take some long exposures of a dam to see how the water would look. However, I could not get the shutter speed below 1/30 because it was too bright. From my research, it appears I need ND filter but I a confused.

I see them in different strength and also single filters that have different degrees. I see Tiffen has a set of 3 but wondering about the quality.

Can someone share their experience with ND filters buying a set of three different strengths as compared to a variable? Is Tiffen a good set for 45.00 for three or do I look for better quality?

As I mentioned in an earlier post, I have a CP, a 4X, 8X and 64X ND, all in 77 with some adapters for some smaller lens openings. Between a slow ISO, apertures of f11 on up to f32 or smaller, it doesn't take much to create the silkiness of moving water. I'm attacheing a series a did a couple of weeks ago, from .625 seconds up. As you can see, at just over a 1/2 second, you get a nice silky representation. At the very long exposures in sunlight, you just blow out the plunge pools unless you are doing HDR with 5-9 exposures. The .625 exposure was at f6.3, up to f36 @ 20 seconds, doubling my exposure time for each photo. 100 ISO and just a CP filter creates all the motion I wanted. I also made a 5 exposure HDR series from -2, -1, 0, +1 & +2. The HDR sequence handles the contrast much better than the individual shots.

Great job on all your work on NDs and how to work with them for Desired Effects.
