Just another suggestion...maybe try not using a cooking pot?
Like, when I see dry ice doing this, with the vapors pouring out of a vessel, it always conjures up some mystical $*** in my head. Like witches making a potion out of frog ears and eye of newt. Or maybe something more alchemical, like some alchemist trying to turn lead into gold. Or hell, you could go the satanic route and this be like the steams of hell pouring out of a portal that some jerk inadvertently opened by reading from the Necronomicon.
Point being...I always thought that dry ice vapors used in this fashion always sort of looked like Hollywood BS. Most vapors that one is likely to encounter don't work that way, it looks fake. So, like, people making movies use it for stories and situations that are obviously fake and total BS. Witches brew, creepy cemetaries just before the monster eats the pretty girl, that sort of thing.
So this sort of begs the question of why you wanted to do this in the first place. Were you looking to do a cooking related shoot? Or did you just think that dry ice looks cool as hell, so you were trying to find a use for it? If it's the former, then you might want to consider ditching the dry ice and using actual steam. If it's the latter, then you might want to keep the dry ice and ditch the cooking pot. This looks fake. You're obviously not cooking anything in that pot, this image was highly contrived and fictional. So...maybe embrace that aspect and just go hog wild. Your methods are gonna make the image look fake and contrived, so why not embrace that and apply the methods to settings and themes which have no pretense of being real?
Thanks for taking the time to write this out, it was a fun project and spur of the moment... Not everything has to look "Real"
