Monochrome Infrared Simulation

This simple procedure describes how an infrared effect may be produced in a monochrome image.

●   Open an image

●   Layer – new adjustment layer – channel mixer – OK

●   Tick monochrome box

- Set constant to +4

- Set green channel to 200

- Set blue and red to -50 and adjust to suit – try -35 red and -65 blue – OK

●   Now to add the “glow”

●   Copy the background and channel-mixer layers and move them above the originals.  The channel-mixer copy should be the top layer with the background copy immediately below.

●   Switch off the original layers and select layer – merge visible to merge the two copy layers into one.

●   Switch the original layers back on.

●   With the merged layer selected, add Gaussian blur – select filter – blur - ●   Gaussian blur and select a value to suit – try 10 pixels radius – OK

●   Change the blend mode of this layer to screen and adjust layer the opacity – 40% works well.

●   Now add a bit of tone

●   Select layer – new adjustment layer – hue saturation – OK

●   Tick colorize box

●   Set hue to around 40, and change the saturation to about -15.

●   The channel mixer settings can be adjusted to vary the effect.
