Martin Evening, in The Adobe Photoshop Lightroom 2 Book, gives a suggestion for an infrared effect. Choose a photo with lots of foliage. You begin by making the green as green as possible by adjusting white balance and tint. Then click grayscale. In the grayscale panel, set the yellow and green sliders to maximum and aqua to 50 or more. Set the recovery slider to maximum. Adjusting the clarity to a negative value will help the image appear more diffuse. You can experiment with the split tone panel, adding a slight blue cast. Note my sample of Lake Pondilla in the Fort Ebey State Park.
