Pan Blur

Pan Blur 1/15th second

Pan Blur gives a static image a sense of motion. This technique works well if you follow a few basic tips. First you need a subject that is moving in a linear line, runner, bike rider, horse, roller derby, etc… Then you need a simple background that will create a streaky blur. So avoid skies or changing backgrounds. A line of trees, field of grass or race track, for example work well. I highly recommend using a tripod so you can pan the camera in a smooth motion.

My technique consists of using shutter priority and setting a shutter speed that is slow enough to allow enough time for me to pan the camera with the subject. The key is to focus on the subject and then move with them as they move. The longer shutter speed creates a blurred background, giving a sense of motion. The subject will rarely be sharply in focus unless you are using a computer controlled unit, like they do in advertising, use Photoshop techniques or get very lucky!

Pan Blur 1/20th second

I start with a shutter speed of 1/15th and go slower from there. There is a lot of trial and error and you need to take a lot of shots to get a few good ones. So keep trying! Next up is zoom blur.

Blurring Action with Shutter Speeds

Waterfall 1.6 seconds on tripod

Last time when I discussed shutter speeds I talked about stopping action to get a sharp image. However, there are times when you want to show motion in a still image. A good way to do this is by blurring the action. There is a fine line between creating an image with too much blur and the viewer asks “What is that?” not a good sign. Or one with not enough blur, the viewer says “That’s a blurry image” not in a good way.

There are several blur methods. Today we’ll talk about the subject moving through the image. I prefer this technique for water and other inanimate objects. Set the camera to shutter priority. Pick a slow shutter speed. What you picks depends on the speed of the subject. I usually start with 1 second for waterfalls and running water or 1/15th of a second for objects moved by the wind and adjust from there. Adjust the ISO to get this shutter speed. It will vary with the available lighting. Finally adjust the white balance for the lighting present.

Using a tripod, let the subject move through the image. Make sure the composition allows for enough room for the subject to move through the image. Don’t get too tight or too far away! Take multiple images and review. Is the blur cool looking or not so great? Do you need to adjust the shutter speed faster or slower?

Next time we’ll talk about Pan blur, this technique works great for some sports and animals.
