Thanks for the reply. So are you only using screw on filters now? Did you ever use grad nd's in the past and have since switched to screw on grad nd's?
Yeap, I only use a screw on filter now. I only use 3 stop, 6 stop and 10 stop. It depends on what duration I want. In low light, a 3 stop can often be more than enough. In full light, I use the 10 stop.
I used 4x6 soft edge graduated 3 stop ND in the past. I thought I needed it when I started doing more complex exposures. But I quickly found it's problems and stopped using it completely at this point. The problem is that it's a straight line. Be it hard edge or soft edge, it's a straight line. The horizon is very often not a straight line. So it's only truly useful if your horizon is straight and has no features, like water. But it's pointless for something with mountain peaks where sky is above and below structures on the horizon. For this reason, I stopped using it. Instead, I just take two exposures and blend them. For anyone that loathes processing, well, fixing a non-straight horizon exposure done with an ND filter takes more processing to fix, so I just went the simpler route at the end of the day--plus I can adjust exposure by any amount, not just the amount of the ND filter's stopping power.
I would -never- use a screw on grad ND filter. The horizon is dead center. I'm not limiting myself to that.
I just use plain high power ND filters. Simple. And if I need different exposure values, I just do different exposures of a scene and blend them if necessary. Though I rarely need to these days. If you shoot RAW, you can easily manage +1/-2 stop exposure difference from a single image. The key is to simply not over-expose (clip highlights) and you can always take exposure down from there. So I expose my images to the right as much as I can before clipping occurs, relative to the duration I'm looking for for the blur effect.
These days, I'm stacking long exposures with a single 10 stop filter to get extreme duration blur effects, without needing any fancy filters beyond a single $70 Haida 10 stop.

Very best,
