Infra-red film effect

This page is part of the 'Converting Colour to Black and White' feature at Northlight Images

Two hue/saturation layers are added one of which does the black and white conversion, whilst the other alters the picture that is being converted -- easier to show than explain :-)

This method is a minor variation on the 2 Hue/Saturation method that I found by accident (I got the blending modes the wrong way round)

Using two Hue/Saturation layers --Other method

Create a H/S Adjustment layer with no adjustment.
Create another H/S Adjustment layer with Sat at -100 Change the layer blend mode to Colour
Return to first H/S layer and tune the black and white effect using the Saturation and Hue sliders.

The image above used Hue +27 and Sat +73
