HI All
Glad to see this thread back!! Anyway to fill everyone in I managed to get a SONY DSCF828 IR capable camera and have been playing with it recently, so I thought I would give people a basic workflow, which is proving quite successful for me at the moment.

Import RAW (use RAW Wb dropper to set balance point)
Increase contrast slider and exposure slider.

Go to channel mixer and use these settings

Red channel

R 0
G 0
B 100

Green channel

R 50
G 0
B 50

Blue Channel

R 100
G 0
B 0

This should produce a fairly flat image, use CTRL+M to open curves, pull the curve to get a slight S shape, Apply this.

Use CTRL+L to get levels.

And done, I would recommend playing round and seeing how things go, but for the newbies this should help take some of the mystique out of using photoshop to edit IR.
