Long Exposure Techniques with ND filters

Arthur Morris' blog today has an informative writeup on blurs using ND filters.
I follow UHH & him daily. Also has had some good recent info on the 7D 2. A great teacher.

Lots of advice already given; I use ND filters when I am forced to, and a good ($200) variable ND filter works fine if you are able to
- set your camera's live view to not show the effect of the aperture so you can still see what you are focusing on
- alternatively focus first at the lowest ND and then progressively dial in more density
- have your tripod mount sandbagged if you are using a long lens, and the lens collar mounted so it is more stable
- use your trigger release with camera in bulb mode, a release with an intervalometer is really handy
The best is to get out when the sun has set or has not risen and use the lack of light to your advantage....less fiddling with filters :-)

the standard rule among we photographers (film) is 1/8th second and adjust, in your case, iso and aperture accordingly

I think we were talking about long exposure though. Yes, putting things on the front of your lens can make cool effects. I used to use the cardboard negative crop guides that the labs provided and sandwich ladies nylons in them, with matchtip melted holes in the center which made a fine soft focus filter....back in the film pre-photoshop days of course.

Dick, if you remain shooting with film, don't forget to add extra exposure time due to reciprocity, but if you are shooting in digital, most shutter speeds slower than 1 second will give the effects that you want. Of course, it also slightly depends upon the speed of the water flow..

I'd suggest that you also purchase Singh Ray neutral density filters as they are the best !

In addition to a wireless release, I use Mirror Up (MUp) to reduce vibrationI always use a cable release---or in a pinch the self timer.

I am also a senior who is an enthusiastic photographer. The issue notes with the "X" in the middle of variable ND filters occurs with certain camera sensors, not all, just some. From what I have read, it has to do with the sensor architecture and pixel placement. Put the filter on your camera and takes some shots, if you get the dreaded "X", send it back and get some regular filters.
For using long exposures, set the exposure without the filter using the auto focus. Switch off the auto focus, and use a $0.99 app on your phone called ND Timer. It will calculate the exposure time and set up a count down timer so you when to stop the exposure. Don't change the exposure by changing the f-stop, only the shutter speed.
Have fun and good luck.
