Hi all,
Just started Photography college AS course in UK.
As such, moved onto digital SLR's.
Got my hands on a Nikon D50
I loved the shots of flowing water and moving clouds by using a slow shutter. However whenever i try my photos are always over exposed. Even though im using iso 200 and f32 (around this).
How slow should my shutter be to capture smooth flowing water or clouds on a windy day, or just people walking so they are motion blurred?
Could anyone recommened any settingings?
Thank you very much for any help
Mark

Using a ND (neutral density) filter will allow you to shoot longer exposures. A circular polarizer filter is a tone down ND filter so it may help a little bit too.
3 second exposure in the middle of the day.

I'd recommend a lower ISO as well.

I used to use a Polarising filter on mine to darken it some more. It worked a treat.

For flowing water, shutter speeds of 1/2 second to many seconds are normally used. The longer your shutter is open, the smoother the water will appear. Cloud movement requires long exposure, usually in the range of 30 seconds or more, though shorter times are possible with very fast-moving clouds. To capture such long exposures in strong daylight you need a *lot* of filtration, perhaps as much as 10 stops.
As previously posted, you can use a polarizer to get a one to two stop reduction in light. That, coupled with shooting near sunrise or sunset may get you where you need to be. The other alternative is a strong neutral density filter.
FWIW, if you want the sharpest possible images, avoid shooting at f/32; try to stay at f/16. At smaller apertures (f/22, f/32), you'll see progressively more softness from diffraction as you make the aperture smaller. |

Thats Brillinat!
Just the result i'm after!
Will try and get my hands on an ND or polarising filter and give that a shot. Thanks for the advice.
Greatly appreciated.
Unfortuneatly the lowest iso the nikon d50 goes to seems to be 200, which i thought was a tad odd...
And i was wondering why they wern't so sharp, will stick around f16 from now on, was just trying to cut down on the light. Thanks for that. Yep, get some filters looks like to be the next step. (got to shoot the subject of 'freedom' for my timed exam, so just trying some ideas)
Anyway, i'll have a mess around with some filters. Thanks again.

Judi's image is a good example of a 'flow' shot and kirbic's advice is on the mark.
One obvious thing to keep in mind is that the amount of motion blur you capture depends on the amount of motion of your subject in the first place. There can be a great deal of variation of that and its a key to a good capture.
Having neutral density (ND) filters and/or a polarizer filter helps when lighting conditions are too bright to take longer exposures. They allow you to slow down the exposure.
kirbic's advice to take near sunrise ot sunset under lower light conditions might be best to overcome bright lighting conditions.
