A month or so ago a member of the Deviant Art community named Frank Piechorowski contacted me about a technique called "IR Channel Shift". It completely blew me away:

After seeing the sample that he sent over to me, I was dying to know how it worked. Frank's response:
"It's easy...
Put a Channel Mixer layer on the image...
Go to the Red channel and make it Red 0% Blue 100%
Then go to the blue channel and make it blue 0% and Red 100%
Short and sweet."
I'm well versed in the ins and outs of Photoshop, so I instantly recoginized Frank's directions. Basically, the IR Channel Shift is reversing the red and blue channels
so that red is blue and blue is red. I read somewhere that this concept was created to balance the red coloring that the infrared filter usually gives digital photography.
It definately makes my digital infrared photographs look more realistic, if only for the fact that the sky is blue instead of red.
Well, whatever the reason, I think it's pretty freakin' cool and have been creating my own IR Channel Shifted photographs:

Frank also turned me on to a few good links concerning digital infrared photography:
Chris M: The IR Channel Shift technique was "invented" by this guy. Pretty groundbreaking stuff if you ask me. I never would have thought to screw with the colors on my own in Photoshop, so kudos to him.
Digital Photography for What it's Worth: More general information about digital IR. I'll definately be scouring this site for information and more ways I can push the limits of digital infrared.
Thanks Frank!
