Flash Photography Tips 5

Now that we’ve looked at the main differences between constant light (Ambient) and flash photography, it is time to experiment with some creative techniques in the wonderful world of flash photography. It may help if you basically consider flash photography as a double exposure picture, with one exposure for ambient light and the second exposure for the flash gun.

It may sound a little complicated and in our Flash Photography Classes we cover this topic in great detail. In the photo below I used ambient light to create a nice, attractive background and fired the flash to light the subject.

By using Slow Shutter Sync, I manage to capture the light reflection and using the flash to capture the model.

What is Slow Shutter Synch?

Slow shutter synch means using a long exposure and the flash to freeze the movement. In the above picture I used a one second shutter speed and while I was rotating the camera, the flash fired and captured the subject. By rotating the camera it captured the lights in the background and created a nice pattern of movement, and when the flash fired it captured the girl’s image.

When does the flash fire during the long exposure?

It’s very important to know how the flash fires during a long exposure. If you use a TTL flash you have two different options for slow shutter synch: First (Front) curtain and Second (Rear) curtain. Most Manual flashes fire as soon as the shutter is fully opened (First/Front curtain).

What is First/Front Curtain?

This is the default setting for the flash synch, manual or TTL flash. The flash fires as soon as the shutter is fully opened and the shutter stays open to capture the ambient light and motion in the scene. It is an easy technique to create some nice effects such as Zoom Burst.

Flash Photography is very creative provided you learn how to control the camera and the flash.

How about Second/Rear Curtain?

This technique is opposite of the First curtain, which means that the shutter opens but the flash does not fire until the shutter starts to close. This technique is very useful to show the motion of an object and the direction of movement. You can use Second/Rear Curtain with TTL or compatible flashes only. You need to set your camera or flash for this function (refer to the camera and flash owners manual for information about how to set Second/Rear curtain)

In this photo the shutter opened, but flash didn’t fire till shutter started to closing and then flash fired to captured the subject.

Learning Flash Photography is a great way to take your photography skills to the next level. As I mentioned before flash photography means a double exposure, one with the ambient light and the next one for flash. The more you learn about these techniques the better you can capture the moment and not be limited by the ambient light. In the next article I am going to explain Off Camera Flash Photography.
