Steven, at this link is a photo I started with, untweaked:

The channel mixing allowed more control for fine-tuning to preference. The final touch, however, for the faux infrared glow, was using a very old filter, KPT 2.0 Gaussian Electrify:

Yeah, it's sort of gimmicky, but my attempt at the time was to work towards reducing the tree's shape to geometric forms, much like Piet Mondrian's early tree studies:

I realize that nothing will accurately duplicate the use of a real IR

on a digital camera, but I like the effect of one but can't really
justify
the expense to get one for my wide angle lens (77 mm filter size). Are
there
any PS Actions that will atleast duplicate/simulate the effect? Thanks
