What ways can photographers effectively use an external flash? The most common technique is “fill flash.” Picture the following scenario: It is a bright, sunny day so you place the subject of your photo in the shade, creating a silhouette. The solution? Fill flash. The flash will send the correct amount of light to “fill in” the subject. Another helpful technique is known as “dragging the shutter.” This technique is helpful when the subject is dimly lit. Slow your shutter speed to about 1/15 or 1/10 and take the shot again with the flash on.
An external flash, like most photography lighting equipment, can soften the lighting. Harsh lights are the nemesis of portrait photographers. Two simple techniques to soften light is to either bounce or reflect the flash. In the first scenario, angle the external flash toward the ceiling. Also, try angling it to the left or right of a wall or into a corner. Shooting outdoors? Many flashes come with a white card built in which extends from the top of the flash head. When you pivot the flash, the card will provide a surface for it to bounce off of toward the subject. The only problem with these two techniques is that the photographer may not have as much directional control. To gain back control, use a diffuser but still point it directly toward the subject instead.
An external flash gives the photographer more control than a built-in flash, allowing the user to have more diversity in his pictures. Add it to your photography lighting arsenal, experiment, and enjoy better, more professional photographs.
The external flash comes to the rescue. It is big and powerful. It has the greater output which means more light. The increased light means that a subject greater distance from the camera can be photographed. The exact distance will depend upon the flash being used and the ISO of the camera. More people can also be covered in the photograph using a wide angle adaptor (available with most external flashes).
The flash can also be used for bounce photography i.e the flash is pointed towards the ceiling or any other surface and the light is reflected from that surface onto the subject being photographed. This is only possible via external as the flash head can be rotated can be used for bounce photography, which is not possible with the built-in flash. The light thus reaching the subject tends to be very diffused and soft which makes the photographs much nicer.
The external flash can also be used as fill in a flash. If your subject is in the sunlight of other strong source of light where the shadows on the face are very harsh, the flash can be used to balance the light and bring out the colors in the dark areas.
The external flash is useble with umbrellas. You do not have to be-be a professional to use umbrellas. You can put your external flash inside the umbrella and connect it via a wire to the camera. When you take pictures the effect will be of a studio light. Another thing which is very in these days is that you can use a wireless connector with your flash and you do not have to worry about the mess of wires around you.

The external flash can let do many of the creative effects you see in different magazines. The slow shutter effect and 2nd shutter are a few. The external flash has a powerful pre-flash which helps in focusing in very dark or contrast situations. The flash fires a small continuous flash so that the camera can focus.
