Yesterday afternoon I ventured down to my local boat ramp to get some long exposures at sunset. I had an ND8 and ND4 (ND is Neutral Density, which blocks light to let you take longer exposures,  and the number just tells you how strong the light blocking ability is) stacked on the 24-70 lens. At 24mm, you could just see the edges of the 2nd filter.

Estimating exposure times is always tricky doing this sort of thing. You want it long enough to smooth out the water, but not so long that you blow out highlights. Thank god for digital and the ability to chimp. This shot was about to be a reject until the bride saw it and loved it. Just goes to show how bad my taste is.

For shots that make this one look pedestrian, have a look at Wisie’s work, he is the long exposure king.
