Long exposures in daylight

I am trying to figure this out. I was trying to photograph a fountain this past weekend using a long exposure..several seconds. I used a large f-stop and tried to capture using 1 second exposure but I keep getting just a WHITE picture. All white nothing more. What is the proper way to take a long exposure mid-day?

If you're already at a large F-stop (e.g., f/22-36) and an ISO at 100, you need to add a ND Filter (3x, 4x, etc.) to the mix to remove ambient light.

set to speed priority and iso 100 and then lower the speed until you hit your max aperture. If thats still not slow enough then you need to either wait until its not that bright out or get a ND filter.

As others have said, however the main thing is ND filters. In bright sunlight however you'll really need to stack them up. This shot was with an ND8 filter, 1/6th @ f22 ISO50.

wow that is a nice picture

great shot

Nice picture!!

I've been there

You need LOTS of neutral density, as that example shows. Here is the logic of figuring how much ND you need...Sunny 16 rule of exposure approximation says that in bright sunlight, 1/ISO and f/16 is used for proper exposure. So assuming your camera is set to ISO 100, you need 1/100. Now step thru the progression of speeds (100-50-25-12-6-3-1"-2") and you have increased exposure by 7EV, so you need -7EV in aperture and/or in ND.

Great explaination Wilt!

All this stuff seems very complicated at first, but it starts to make sense when you start thinking about how you are just playing with the amount of light through different limits that you have at your disposal and that most deal with doubling or halving the light.
