I think I've hit on a solution to the real fire connundrum, but I'm still perfecting the technique that will be used to make it. I'm not sure if it looks completely real though, so can someone tell me if it could pass for fire?

Maybe change your post first so that we don't have to scroll 2048 pixels sideways because that's really annoying and you know it!

Those are pretty good, I think the first one is better than the second. I think it has something to do with the colors of the flames more than the shapes though. I would be curious to know what you did to achive that look, if you care to share.

I know it has more two do with color than shapes, but I'm still working on the color theory. I want to try to make this completely realistic.

Without a explicit visual guide to the scale of the flames, im feeling the scale by looking at the detail of the flame shapes. Due to the fairly smooth curves of the flames and general lack of turbulence, the flames look pretty small, flames that one might find on a match stick, burning paper, or maybe burning oil /alcohol on a petri dish.

In either of these cases i note some problems with the flames. Firstly the flames are too saturated and opaque for such small flames. Secondly as both have fairly wide bases and as such cant be a single flame, they could either be oil or burning paper. Now again for either of these its too bright (for oil it might be ok) but also the flames are too coherent near the base.

I think the major thing to point out is fire doesnt excist in a vacuum (literally as well as metaphorically). painting how the environment is seen thru a flame is just as important as being able to paint the flame in itself. For instance the bending of light due to heat is qute a large part to a convincing multiple flames.

With candles i think one can get away with a black background, but eventhen you want to mimic the SSS of the wax.

So yea provide some context and then it will be easier to judge/improve upon.

Thank you, that was very helpful, but I just have one question: What kind of flames do large fires have, if small are smooth. I though all flames are smooth.

For instance these photos shows the small scale turbulant detail in large fires.
