A polarizer lens coupled with a small aperture setting can be usedto slow down shutter speed and blur flowing water to get someinterestingeffects. Thanks to image stabilization these were taken handheld at 1/10s- 1/15s. Aperture was set at f8. It was overcast which further reduced the amount of light. I also fiddled with exposure compensation to get the slowest handheld shutter speed without overexposing.

5x zoom, ev+1/3, 1/15s

Excellent shots and Technique, the blurring on the water is cool.
Great shots and also a tutorial on how too.

very good!
I hope my two crossed polarizers will be with me when I find such a place!
My two gray x4 filters are not dark enough!

Nice photos, long exposures are always fun to play with.

Sven, Two linear polarizers crossed will reduce the amount of light a lot more than a ND8. The only issue is when at 90 degrees ie full cross polarization a blue tint appears, I find uing a bit off full works wlll though. I have posted an example earlier.

The sun was fairly bright (11AM) though it wasa little overcast.The one polarizer got the shutter speed down about as far a you could go handheld - I could get it down to 1/8s. As long as there weren't any bright areaswhich wouldoverexpose, this worked fine. I thinkstacking twopolarizers might cause some vignetting and probably are unnecessary if the ambient light isn'ttoo bright.

thanks Fred,

I am sure you are right!

But my gray filters are too weak and I wanted to do some shots in bright light...

I will test my polarizers and report about it.

My second thought was to use a tripod and superimpose some pictures in pp, the variable parts should blur. Has anybody tested this idea?

That is really a nice effect.

I did some stuff with waterfalls this spring and a ND8 and a ND4 were not enough if the falls were in the sun. As I was trying for a 1/4 second shutter speed , so I bought another ND8 but have not got to try them yet. I have a lot to learn about that,but I do like the effect you achieved.

I understand the Ideal way is to wait until the sun is not a factor but when I am on vacation that is not an option.

Gene - Always sunny when you're on vacation? That's a bummer.:-)

Most of the shot is of white water and there is quite a bit of light there.So a cloudy gray day or late in the evening or early morning should provide the right amount of light.
