Hi all, went to a training session today at work involving people inside a building and working in white cosmetic smoke, the guys had torches fixed to their jackets. The photos I took are good and not bad but nearly all the amages came out looking with noise, even though the iso ranged from 400 to 800 around f4 - f2, shutter from 50 to 80, the histrogram looked ok I also switched between M and A. Some were taken close up so you can see the markings on the helmets. I would post some of the images but they are copyrighted to work.

Any ideas what settings I should be looking at? I might have to do it again

Can you not reduce it in whatever software you have ?

If by chance it is Lightroom 4 then it can probably be fixed without too much of a problem.

We're you using flash? Stage smoke is very fine droplets suspended in the air, the noise could be light reflected from inside the droplets (cats eye effect).
Using an off camera flash might help

I am not sure what the problem is. If the issue is with noise, then going up on ISO certainly wont help. Taking it off AWB won't help either.

Also, even without using flash, as Richard mentioned, smoke is fine droplets in the air. So, what you mentioned as noise is probably not noise after all.
