A Flash In The Night
Create dramatic evening images with a touch of artificial light
It's also an effective way of eliminating shadows on the background created by the subject when the flash is coming directly from the camera's position. By situating the flash higher than the camera, the shadow will be cast lower, behind the subject, and won't likely appear in the final photograph.
Bounced And Diffused Flash
Another way to change the quality of the light emitted by the flash is by bouncing or diffusing the light. For example, by using a diffuser over the flash head, you can soften the appearance of the light when working with close-up subjects. The harsh look of flash can be markedly reduced.
Bouncing the flash into an umbrella, a white ceiling or a wall emits a diffused source of illumination. When bounced off a reflective surface, the light is diffused and produces a softer, more even illumination, which can be particularly flattering for portrait subjects. However, the diffusion that improves the quality of the light also reduces its effective range, so your subject may need to be closer to the reflective surface than it might have been if you had used the flash straight on. Also, be careful that the wall isn't tinted, as that will produce a color cast in your final image. When utilized off-camera, the flash can be directed to bounce more easily off some surfaces, providing you much greater control.
As you experiment with each of these techniques, you'll discover the variety of ways flash can produce distinctive looks in your nighttime images. Especially when used in combination with each other, these techniques will result in unique and outstanding photographs.
