The best part about learning rules is breaking them. For example, most of the time, blur in a photograph is a faux pas. But there are ways you can use blur to add energy and emotion to your images. In this lighting diagram, we will explore how to introduce blurring to your images with the use of an on-camera flash.
Before you start experimenting with this technique, make sure to go to you menu in your camera and set it to "rear curtain sync".
This will allow your flash to trigger at then end of your exposure, rather than at the beginning. This will help your subject stand out better and not get lost in your image. The length of your exposure will depend on how bright the ambient light is where you are shooting, but I like to be around half of a second.
This dragged-shutter effect can be done a couple different ways. One way is tracking with a moving subject. This causes the blurring to mirror the movement and direction of the subject. This is a great technique to use at the end of wedding receptions, when lighting is low and you are trying to capture the excitement of the bride and groom running off together.
The second technique can be done with moving subjects but is also effective with inanimate objects, as in the shot below. If you have a zoom lens, like a 24-70, you can zoom in to 70mm before you begin the exposure and then zoom out to 24mm as the exposure is taken.
This is a fun technique to experiment with. I'd love to see your images in the comment section. Have fun!
