If you don’t have an ND Filter…
Sometimes, you can use ND Filters in the middle of the day to get long exposures. This shot below wasn’t exactly the middle of the day, but it was pretty bright outside. For those of you that aren’t familiar with this ND thing, it stands for Neutral Density, and it is basically a dark filter on the front of the lens that limits the amount oaf light that comes into the camera. This means you can have the shutter open longer to get things like streaks in water. Anyway, you can get around that a bit by just setting your fstop as high as it will go, like f/22 or higher, for example. This will let you make your shutter speed longer and get a bit of the streaky effect.
Daily Photo – The Island Cave
This photo was only 0.8 seconds long, even though it looks like a bit longer. When the waves are coming in at a good click, you don’t need a super-long exposure to get this effect. You do need a tripod, though. I think it’s impossible for a human to hold the camera still for 0.8 seconds! This is down on one of the many beaches in Big Sur, California
