So here's the PSD file for "Fire." I decreased it's size a little so that the file wasn't so big. *based off of techniques as seen in advanced photoshop magazine.
NOTES:
- the layer "lens blur" is an applied image. hide this layer to be able to see the influence of the layers beneath it. the edges of the arms on the model were hit with blur tool beneath the gradient tool (hit key R) to blend her into the scene better.
- the "channel paste" layer is a copy-paste of a duplicated blue channel that has had the levels tweaked.
