types of flash

Most cameras come with a built in flash for photography needs.  Many point and click cameras do not allow for an additional flash attachment, but most of the newer point and click cameras have a master/slave frequency  which allows for a handheld flash to trigger.  I was recent the photographer for a family photography session and had my studio lighting set up for the event.  After I was finished taking photographs of the family, some of the girls brought out their cameras to take extra pictures for themselves.  I was surprised when my lights synced up with their cameras and started flashing with their shots. 

Other available flashes are S mount flashes for more advance cameras.  Look for generic versions available at your local electronics stores.
