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

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
