LDR's are not designed to drive another device/load directly, its required that a transistor or simple amplifier is used between the LDR and the 'load'.

"I just need a circuit that's like this, Light falls on the LDR, then just shorts the circuit."
A simple circuit, i need it to use for an external flash with my camera. The LDR will be mounted on my camera's built-in flash, then as the flash fires, it triggers the LDR to short the connecting leads on the external flash, so that the external flash fires too.
