DSLRs and pyrotechnics

[Noah Kadner]

Definitely shoot some tests- there’s rolling shutter to be concerned about and also of course basic safety issues that sometimes get lost if you’re talking low budget…

I don’t think you’ll have the same issues.

The strobe light problem is caused by the lighting pulsing flashes of light that are faster than the shutter speed, therefore causing only the portion of the chip that was exposed during the pulse to be exposed.

Pyrotechnics are constant burning sources of light with no pulse similar to tungsten, essentially just fire light.

Thanks Noah! Safety (hopefully) shouldn’t be an issue. They’ve got a professional on set…

Thanks, Phil! Yeah, that’s exactly the problem, I was worried about!
I’ll talk to the pyro guy what he’s about to use.
So we’ll better avoid fast flashing pyros and stick to more or less constantly burning stuff.

IMO, it shouldn’t be any different than shooting fireworks, which is basically what pyrotechnics are. If you can find the proper shutter speed for fireworks, I would think you should be good to go.

Even a fast flashing pyro won’t fade fast enough to cause a problem, with strobe we’re talking 1,000ths of second.

I would however talk safety issues with the pyro guys. ie how close etc is still safe.

Fireworks. Yeah, that’s the solution! Thanks a lot, Chip!

I guess, that’ll be my starting point in research!

Thanks again, Phil!
The pyro-guy does a lot of stage-effects and seems to be pretty experienced. But we will definitly have a “safety-meeting”, since neither the band nor the guys behind the camera(s) have worked with pyros before.

So thank you guys for your input! Much appreciated!
