does anyone have experience and/or recommendations with regards to ND filters and daytime long exposures?

10 stop would be a good start. I was using a 3 stop ND for video work and outdoors that barely got me down to 1/50, iso 100, f/2.8. However many times that wasn't dark enough to maintain the shutter speed.

I have the 58mm LCW Fader ND Mark II. The image quality takes a very small hit when using the Fader ND, but certainly not enough to keep me from using it. Autofocus doesn't seem to work well when using the Fader ND (no matter what the opacity is), so I use a tripod, manual focus, and Live View with 5X (or 10X) magnification.


Here are some shots where I've used the 58mm Fader ND Mark II:

Hi,


I quite like the waterfall experience but the brightness and contrast issues always play havoc during open sunlight and from where I am from, there is alot of sun. I have had success using low ISO, a 0.6 (?) ND filter and stacking a polariser on as well. I get the water trails and the look after trial and error. Water spray is something else!





Good luck

thanks everyone for your replies! I think that a 10 stop will be the best one for my needs based on your guys responses! I do already have a good tripod and fully plan on using it for the long exposures. Thanks again everyone!

You're going to have a blast. I do a lot oflong exposures (timelapse photography with 180-degree shutter). One of the difficulties you may encounter is infrared contamination in the form of reduced contrast and shifted colors. Normal ND filters only block visible light, so a 10-stop ND filter increases the amount of infrared light by 1024 times! Normal amounts of infrared are easily blocked by the sensor's IR filter, but at some point it's not enough. The only solution I know of is to use "hot mirror" and other IR-blocking ND filters which unfortunately cost quite a bit more than regular ND.
