Sparks


Recommended Posts

I have a scene in an up coming shoot where the only indicated light source is a lighter that one of the characters is flicking it to light but it wont ignite. I was wondering if anyone knew of a good way to augment the spark effect of the light if the source (the lighter) is off screen or hidden behind the character within the frame?

I was thinking the actor would use the button to "flash" the flashlight. The beam from the scorpion is pretty focused, maybe only about 1-2 inches even a couple feet away, so it wouldn't fill up a 5" card.

 

I guess I was thinking the spark would only have to light up a small area close by, like the actor's face, or something he's holding it near to see with the flame. A spark isn't very bright, so I didn't imagine its glow would need to carry very far.

 

We've talked about flash gags before, and it's always a matter of the filament size. The larger the bulb (filament), the longer it takes to come up to full brightness and back down again. Strobes of course work a little differently.

For some coverage it doesn't need to travel far. But for one of the shots it needs to spark up the whole room to reveal another character in there. I'd like to have the character that?s lighting the lighter's silhouette (she?s on the floor) in the foreground and as it flashes it reveals another character in the background.

 

But the only way I can see to achieve this, and I?m not sure it will work, is having a lamp op handheld a leko with a 19º barrel off screen but still in the back. Build a bottomer, siders, and toper with a small hole in the middle for him and have him pan his leko into the gold bounces that are placed next to the character on the floor, but hidden in front of her away from camera; and as the lamp op pans his leko in the hole, he wipes it back into the solid sider and repeats giving the sparking effect. But I see problems that I can comprehend right now.

Panning or flagging gags usually don't work convincingly for a something as quick as a lighter spark. If you need more output with a quick flash then you're probably talking about some kind of strobe unit.

 

But creatively it seems a bit unrealistic that a lighter spark would light up more than a couple feet around the spark itself. The effect you're describing is beyond what we could realistically see with our own eyes even in a pitch-black room, but then maybe that's what you're going for.

Hey guys,

 

I have a similar need in an upcoming piece where a guy is getting Tazered. They

plan on putting it in post (both shots are really, really tight) but they are hoping

for some practical flashing (bluish light, quick flicker). Would a scorpian work for

that? Is there a better solution?

 

I'll also have to create a flash for a gun shot in a later scene. Is that a lightning strikes thing,

or is there a better solution for that?

You want the off camera light to appear to have come from the striker of the lighter, just substitute a gas torch striker for the lighter. The flint is larger and it produces a larger shower of sparks reliably. You could even use multiple strikers to increase the effect. Cost is a few dollars or free if you borrow them from prople with propane or oxy/acetylene torches.

We've discussed gun flashes and electricity gags many times before, so try a search.
