What do you mean by flash exposure. as far as i know exposure corresponds to the amount of light reaching the film with respect to its speed. it can be changed by changing the shutter speed and apperture. but i don't understand whats an X sync, what do you mean by setting flash apperture. i have gone through bob atkins site on flash photography. but i didn't understood clearly these concepts of *X-SYNC* and *FLASH EXPOSURE*. can anyone explain what happens INSIDE THE FLASH when i set shutter speed and apperture, manually, automatically or semiautomatically.

thnx
