Hi..just wondering if its possible to shoot long exposure shots in broad daylight? I wanted to shoot the foliage of the clouds just like those at night..but obviously when using lower shutter speed, it tends to be overexposured. Even using highest f stop doesnt seem to work.

Is there any way? Any one tried it before?

There is something called a ND filter which blocks out lights coming in to the lens.There are filters like ND 8 ND 110 so on and so forth.The lightest is ND4 IIRC.The higher the ND XXX the more light it blocks out

Need to use ND filters. Possibly even stacking more than one.

Get a 10 stop ND filter, with F22 you should be able to get 10" or more.

Lowest ISO + small aperture + relevant ND filter

Get a ND110 from B+W or a Hoya ND400. They reduce exposure by about 10 stops and 9 stops respectively. Allows you to make 30s exposures in the hot afternoon sun at f8/f11

you sure?

without ND100, minus 10 stops, try shooting any outdoor scene on a hot afternoon sun with ISO 100, f11 at 1/30s, see what can you get.

to TS, check this out, Exposure value

base the EV of the scene, eg Typical scene in full or slightly hazy sunlight (distinct shadows) is EV15, and to get the slow shutter speed effect you want, you can see how many EV you need to cut down, from there, you will know which ND filter and how many of filters you will need.

I mean calculate 10 stops down, see what shutter speed you will get.

anyone has a camera now, can take a meter reading of a tree under the sun outside you window, minus ten stops, see what can you get.

Ok..will a ND8 be enough?
ND8 means 1/8 of light is passing through. This equals 3 stops, not enough if you look into the table at catchlights' link. ND400 will cut about 10 stops, enough to get several seconds exposure time in daylight with f/11 and ISO 100.
