Exposure Stacking

I learned a new technique this weekend. Well, not new, but new to me. It’s called exposure stacking. It’s a method of combining several exposures into a single image. Why? Read on! I wanted to go for a silky-smooth water effect with a neutral density filter that allowed me to keep the shutter open for several seconds. The problem with just shooting this way straight up is that there are other things in the scene moving and I didn’t want those things blurred by motion.

So for each of these shots I took two exposures. A quick one and a long one. I combined them into Photoshop layers and erased all but the water from the long exposure, so the quick exposure signed through on the rest of the image. I’m pretty pleased with the results I got. I hope you like them.
