Ok stupid question...how did you do that? I tried doing similar today, but the end result I got was an entire picture over exposed. The running water got that effect from the long exposure, but everything else is over exposed.

hi charlie,
select S mode (shutter priority), and try setting the shutter speed to say 1/10. the aperture will be automatically set for you preventing over exposure. a slower shutter speed will smooth out the movement of the water even more. set metering mode to matrix, check the results and adjust accordingly. shoot in raw which will enable you to lift any shadows or reduce any highlights in post processing.

He might have used an ND (neutral density) filter, which is like Sun glasses for your camera. They come in different strength (2 stops, 4 stops, ..) and allow you to double, triple, etc. your exposure time.

hi charlie,
select S mode (shutter priority), and try setting the shutter speed to say 1/100. the aperture will be automatically set for you preventing over exposure. a slower shutter speed will smooth out the movement of the water even more. set metering mode to matrix, check the results and adjust accordingly. shoot in raw which will enable you to lift any shadows or reduce any highlights in post processing.

That would explain it ... I did go to shutter priority, but my shutter speed was probably too slow for the camera to compensate via aperture. I'll play with this some more tomorrow. Thanks for the help!

The light in the spot where you are taking photos will determine what shutter speed etc you need to use. In full shade with just a polarising filter, you can get quite slow shutter speeds, down to a couple of seconds, but if it's sunny you need more light filtering, and you tend to get blown out highlights (like you have in the top 2 photos).

Set ISO to 100 and aperture to as high as you can with the lens you are using eg 22 and start from there with shutter at 1/5 say.

Shutter speed also determines effect. At 1/5 you get good definition of the water movement and as shutter speed gets longer after that you start to get that milky effect. You don't seem to get much more benefit by going to slow with the shutter unless you want the real misty milky effect, and then you need an ND400 filter so you get go the shutter speeds of say 30secs. If you do try an ND400, especially out in the sun, remember to block the viewfinder on your camera :D

I'm not very good at explaining how to do stuff so I hope this makes sense.

Hey guys, thanks for the tips on uploading. As far as how the shot was taken: 18-55mm kit lens on D3200. Tripod. No neutral density filter. I used full manual mode. Shot at shutters anywhere from 1/5 to 5 seconds and stopped down aperture anywhere from f22- f32. Just took a whole lot of pictures, lots of trial and error. Please let me know what you all think of the shots, good and bad Thanks!! Dustin

hi charlie,

mistake in my original post. should have written 1/10th instead of 1/100. let us know how you get on in any case, looking forward to see your photos.
