for you guys who wanna make ROTS-like lava in photoshop, try this out
choose medium brightness orange
black background color
filter-render-clouds
filter-render-difference clouds a few times
up the contast (enhance-adjust lighting-brightness/contrast) until you see reds, ornages and yellows but not too much
use filter-sharpen-unsharp mask to the settings of your choice and there you go, pretty good looking lava
(i used elements 3.0 so yours might be different
