When photographing at night, flash photography is often used to illuminate the subject. There is, of course, more than one way to do this. One option can be to use an off-camera flash to backlight the bride and groom to create a silhouette shot. Flash can also be used in darker conditions to create stunning high contrast photographs. Remember to look at what ambient lighting your venue has. Signs and outside lighting can make for some striking and memorable images. Other light sources can be used to make interesting and dynamic pictures, such as string lights, lanterns, sparklers and candles.
