Image shot with a converted Canon D60 and a Canon 75-300mm f/5.6 lens at 155mm, f/4.5, IS0 200. If you mouse over the image, you will see that the background of the Raw file is brick colored while the leaves are white and the butterfly is black and white rather that black and yellow.
Using Nik Silver Efex Pro 2.0, I converted the image to black and white with the filter Film Noir. If you would like more information on Digital Infrared photography and what cameras are best for conversion, listed are several sources.
