Black Marker illustration, scanned into photoshop.
Red photoshop brush background, multiplied the flames layer.
Added Orange on another layer, wiht the same brush.
Added Yellow on another layer, wiht the same brush.
Screened the layer, and hey presto we have FIRE!!!
I’m a pyromaniac at heart!
Multiply – means to turn what’s white transparent so other things can show through.
Screen – same as multiply, but turns what’s black see through.
