Does anyone know the best way to produce a realistic gunfire flash off camera.
I need to do a shot of a soldier firing a gun in the air at night...the gun will be off camera as he raises his hand with the gun

I'm sure we've discussed this before. Try a search, probably a couple years back. I know there's lots of info burried there somewhere..
I've done it with a photo flash on the highest setting gelled with 2 layers of full straw. We just did it until I, after a take, asked if the flash went off because I couldn't see it (i.e. all of the flash's light went onto film rather than the eyepiece)
There's probably a better way but it worked well for us students on a budget.

-oh, just read the gun will be off-camera. Yeah in that case, any light you can flip on and off rapidly, that should be simple to set up.

You can buy blank-firing weapons that are considered non-guns because the barrels are plugged; you don't need a liscence for them or a pyro on set because they're not considered firearms.
For clarity -- and safety -- a "non gun" is NOT a "blank-firing" gun with a plugged barrel! A non-gun never was, never will be, and doesn't work the same as, a real firing weapon.
A non-gun is essentially a "cap gun" that looks very convincing on camera. Don't make a potentially deadly mistake between a "blank firing" firearm and a "non-gun." "Blanks" are real charges, and have been deadly on movie sets (John Erik Hexum, Brandon Lee).

The production tried to use a photo flash for on-set gun flashes but only managed to capture one for the shotgun blast. Photo flash times are so fast that catching one in-camera is troublesome. I've used double strobes for electrocution effects by setting them at twice the speed I wanted them to appear on film later.
I recently used a 1.5W Luxeon LED flashlight for a nighttime gatling gun flash effect. Just positioned the flashlight out of frame and rapidly bumped the back button.

Check the ending scene of 'Jarhead'. Those effects look asthough they were done with a camera flash. (More like strobe)

Blanks look great, but motion pictures are avoiding using them too, Pay Back, Pan's Labyrinth, etc. It just saves money on permits and means that there is no danger involved. There are also guns that just make a flash, but no sound, or chamber blow-back.
