Bounce flash is an easy and effective lighting technique. When the flash head is rotated to bounce flash position, you can bounce the flash off the ceiling or a wall to soften shadows and produce a more natural-looking picture. It’s easy and brings a whole new element to the enjoyment of photography.
Because bounce flash does not illuminate the subject directly, there are no harsh reflections that direct flash can cause.
Reflections are caused by direct flash light. You can also use the remote flash technique to avoid reflection by changing the direction of the light.
