I use a modified Canon EOS 20D to capture infrared images, which are then processed in Adobe Lightroom. I shoot in RAW, and the images, when imported, are various shades of red – as would be expected. From this state they can be converted to monochrome (either shades of gray or other subtle variations) or to false colour images. There are various ways of doing a monochrome conversion. One way I have found useful is to create and apply a camera profile.
