Most of the time movement in your photographs is a bad thing. That’s why we use tripods, shutter release cables, good lenses , and even lock up the mirror, etc.…. to reduce any movement or shake in the image. However, sometimes movement in the photograph can be very cool for artistic and creative effects.
Here’s a recent shot where I used a very slow shutter speed at a very small aperture to create movement in the waterfall behind the model. The camera settings were 1/8 sec, F32 @ ISO 100. I had to go all the way up to f32 to be able to use a slow enough shutter to get the desired amount of movement in the water behind her. Let me know what you think.
