Use an External Strobe Light to Offer Your Photograph Much More Then a Built-in Flash
How to effectively use an external strobe light to offer your photograph much more flexibility over a built-in flash.
Strobe lights normally fitted into a standard camera are rather weak. An external strobe light will be will offer much more power. This extra strength will let you photograph subjects from much further away. It also allow for much more flexibility to use lower ISOs or smaller apertures in your photograph.
An external strobe light also gives the possibility for "swivel" or "bounce" options. A direct flash results in very harsh lighting. When there is no alternative, this might be acceptable, but it is never an attractive option. However, an external strobe will allow you to rotate the flash and bounce it off a nearby ceiling or wall. This will produce a much more natural looking and softer light in your photograph.
This is the key advantage to using an external strobe. Remember that bouncing the flash around the room will greatly reduce the strobe intensity, so it is very important to choose a powerful model if you are going to use this technique.
A quality external strobe light will also offer more versatile operating modes that are not available with a standard built in flash. SLR cameras are limited by their shutter design to a maximum shutter speed at which flash can be used of about 1/125sec, depending on the camera. Using these shutter speeds, there is a slight risk that some subject movement will be picked up. If the strobe is being used to provide "fill-light" for outdoor portraits, the speed is also a serious limitation. Many external strobes offer a "high-speed sync" mode that will enable you to take advantage of much higher shutter speeds.
Some models of external strobe also offer a repeating flash that enables you to capture multiple images of a moving object during a signal exposure. This can be an essential feature if you are photograph features a subject moving at high speeds in poor light conditions.
Flash Power Values
The power of a strobe light is measured by "Guide Number" (GN), usually measured at ISO 100. This number can be used for many exposure calculations, making it a useful standardized measure of flash power. For example, divide the guide number by the subject distance, in meters, to work out the correct lens aperture to use.
A typical built-in flash will have a GN of a round 12. This means that to photograph a subject 2m away you should use an aperture of 12 divided by two, or about six. Most modern external strobe lights will carry out these types of calculations automatically.
