I have recently had experience with others who are using off camera flashing (strobing) by using a fitting on their camera to transmit a signal to the light source as the exposure is being taken.
i would like to do the same thing by putting an optical sensor in front of the flash, the drawback is that the flash does an exposure calculation first before firing again when the exposure is taken
My question is this, does anyone know how to cancel the exposure calculation flash at source? I believe I can solve the other details.

thanks
