Colored Fog

AEA doesn't have an issue with fog they just regulate it for health and safety reasons. The paperwork that is available on their website is based on the testing done by Environ, and independent company, for AEA. They tested, and continue to test various fog and haze machines for the particle concentration of the fogs and hazes based on the safe levels for breathing. There is also documentation on how to perform your own testing if your machine is not listed.

The calibration factors document from the above link details how the air quality meters were set up for the testing. There are also equipment based time and distance reports available for download. These detail when you can put an AEA actor in front of different machines at different output settings.

 

ost likely it was a version of "spectra smoke". Spectra Smoke or smoke cookies are available at a number of places, anyplace that does video or film. it usually comes in a 3 1/2" x 3/8" Cookie. we used to use a pair of vise-grips to hold half a film can light the cookie, then put it in the can lid, then use the other half of the lid to wave it around the set. There are a ton of ways to get this kind of smoke, but as there is a prohibition against Pyro on here, and all of these methods involve lighting something on fire or igniting a chemical, I shant discuss it further.....

 

As was suggested above, with all the CGI in that movie why would they deal with the hassles and hazards of real smoke? Just draw it in later, it'll look more like real smoke than real smoke does.

 

And you don't have a bazillion dollar budget like they did.

Look at it this way, how much in that same shot was CGI-ed in later? Was anything real in that shot? How can you know anymore?

 

Are angels not entitled to days off?

And I thought God gave people wisdom for a reason...

 

The fact that this question is being asked is of slight concern... You have wisdom to know that playing with flaming swords comes with a high chance of burning the building down or some other disastrous consequence and should then be able to, through said wisdom, that it might be a good idea not to do it...

 

Let me echo my apologies for the misinterpretation posted in the other thread and refer you there for further details...
