TLR Faux Infrared Want to experiment with the B&W infrared look but don't own a digital camera compatible with infrared photography? You're not alone. Expensive DSLRs and digicams have a powerful IR blocking filter to reduce moiré artifacts. In many cases, this filter is so powerful, IR photography is impossible or impractical. I've been experimenting with different techniques for simulating digital infrared. The result of my research is the TLR Faux Infrared action set. Be warned! This action set requires that the image be 8-bits per channel. A warning dialog will remind you that the action should be run after you finish your major edits to tone and color. Faux Infrared Actions There are 21 different actions in TLR Faux Infrared. Portraits and landscapes typically require different conversions with the Channel Mixer command. Portraits make heavy use of the Red channel, landscapes of the Green channel. You can choose five different settings for each, with low grain and high grain options. There is also a Manual action that you can tweak.
When you run one of the TLR Faux Infrared actions with Adobe Photoshop CS/CS2/CS3, the layers will be placed in a Layer Set/Group. Earlier versions of Photoshop will not have a Layer Set/Group. All work is done non-destructively with layers. Three layers are created for the faux IR effect. A Channel Mixer adjustment layer is used to convert the image to monochrome and to adjust the faux infrared tones. Gaussian Blur is applied to a pixel layer to soften image features, a characteristic of infrared images. You can adjust the opacity of this layer (or even its blend mode) to adjust the infrared effect. Diffuse Glow is applied to the third layer. This adds the glow associated with halation effects of infrared film and also simulated film grain. By default, an Overlay blend is applied to the layer. You can adjust the layer opacity, layer blend mode, or Blend If sliders to alter the faux IR effect.
Available Settings You can choose from five different settings for landscape images. These settings can also be used with still lifes and other objects.

Grain IR Effect Manual Adjustment If you prefer to "roll your own" saturation settings rather than selecting a preset faux IR effect, TLR Faux Infrared includes an action for manual adjustment that takes care of all of the mechanics.
