Take an exposure without firing the gun so there isn't any flash. If you see the balloon you are getting an ambient light exposure. You fix this by increasing the flash to ambient light exposure ratio. You do this by reducing the ambient light or by decreasing the shutter speed or by closing the aperture while raising the flash power.

If the exposure is pure black then the flash is firing two times - once when the bb gun fires and once when the balloon bursts. If the flash is firing at 1/4 power or less this is well within the capabilities of a hot-shoe flash.

Living and loving it in Bangkok, Thailand. Canon 7D - See the gear list for the rest.

Good points! I'll try and do that this evening and report back. Thanks for the input!!
Actually the flash is off camera and the flash is hooked to a Hiviz sound trigger ..
