How can I take a longer exposure in daylight, without blowing out the picture completely? I have messed with a combination of settings, but I cant get it right.
*edit: typo on the title...ANSWER instead of image*

small aperture vs. long shutterspeed.
if that's still too light, try a filter (grey-filter?) that mightt work too to hold a stop or 1,5 |

| Filters, filters, filters. Neutral density, stacked. Gotta knock the light levels waaaaay down. |

Neutral density (ND) filters. "Neutral density" just means it's not colored - that is, it's gray.
They're often marked in terms of how much they cut the light. For example, my 4x ND filter cuts the light to 1/4 of actual, allowing me to quadruple the normal exposure time.
You can stack them, which multiplies the effect, so a 4x on top of a 2x yields 8x, or 4x and 8x yields 32x.
You can also stop down, using a smaller aperture (larger F-number).
Those two together are how I took this shot in early morning but still got a long exposure so the water blurred:

Neutral Density filter (or several)
Used on their own or in conjunction with a polarizer
Or use just a polarizer
It depends on how much you want to slow down the shutter speed.
Taken during the day with 2 ND filters and a polarizer:

Heh! Just found exactly that point in a blog entry:
Gray is a color.
Grey is a colour.
But the difference is that both "gray" and "grey" are acceptable in American English, whereas only "color" is.

Is this true? If you stack a 1x on a 2x, don't you get an equivalant of 3x? Therefore a 2x on a 4x would be a 6x, not 8x? |

Careful - there's "x" ratings and there's "density" ratings. "x" indicates the actual multiplier, not the number of stops. So 4x means 1/4 of the light. But a 1-stop filter means 1/2 the light.
x multiplies, stops add.
2x + 4x yields 1/8 the light.
1 stop + 2 stops yields 3 stops, which is also 1/8 the light.

I have habit of spelling them colour, neighbour etc etc, and my spellcheck keep telling me spelling error. Its irritating. |

Ah-ha! There we go. I have stopped ND filters. Thanks for the clarification.

You can add the words with the English, UK spelling to the dictionary of the application you are using and avoid those warnings.. I have even added my name, company's name etc to my custom word dictionary to avoid those irritating messages. |
