                          Front and Rear Curtain Synchronization Some cameras offer the option of rear curtain synchronization (Rear mode) triggering the  flash unit at the end of the exposure time. Rear curtain synchronization is particularly  advantageous when using slow shutter speeds (slower than 1/30 sec.) or when shooting  moving objects that have their own source of light. Rear curtain synchronization gives a  more realistic impression of movement because the light streaks behind the light source  instead of bui

                          Bounce Photography Using direct a flash to illuminate a subject will result in harsh,  unnatural and unattractive shadows. This can be avoided by  using bounce flash. The head of your flash can be tilted to an  angle of 45°, 60°, 75°, or 90°. You can tilt the flash head to  bounce the light off the ceiling or walls. While shooting indoors,  this technique can help to create more natural looking pictures  of people with softer shadows. In order to have your pictures correctly exposed using boun
