The "infrared look" in photography is a terrific alternative to traditional color imagery. There are many paths you can follow to experiment with the IR alternative. The pure approach is to actually shoot infrared with a digital camera.
You can purchase a very dense Hoya 52mm RM72 Infrared Glass Filter and put it over your lens. Some cameras work better than others in terms of displaying the IR effect. You can test your candidates by pointing a TV remote control toward the lens and seeing how bright the dot of light appears on the camera's LCD screen. The brighter the dot, the better the camera will record IR.
You can also have an existing DSLR modified for IR photography through 3rd party services such as Life Pixel. If you want to get serious about IR, this is the best way to go. They remove the IR blocking filter inside the DSLR so you can shoot normally without having to put that dense RM72 filter over the lens.
You can read more about ways to capture IR in my Macworld article titled, Photograph the invisible with infrared photos.
If you're not interested in dense filters or modifying cameras, you can fake the IR effect using your image editor, as I did with the shot of the Bodie House shown above. I created that effect in Aperture using these simple steps in the Adjustments panel:
- Enable the Monochrome Mixer in Aperture. Move the Blue slider to -20 and Green to +80
- Switch to the Color adjustment brick and click on the Green square. Move Luminance and Saturation sliders all the way to the right.
- While still in the Color brick, click on the Yellow square and move the Luminance and Saturation sliders all the way to the right.
- And finally, in the Color brick, click on the Blue square and move the Luminance slider all the way to the left and Saturation slider all the way to the right.
- Now play with your normal image adjustment controls, such as Exposure and Enhance to perfect your photo.
You can even create fake IR on your iPhone using applications such as Photo fx 2.0. I go over all of these techniques in my Macworld article titled, Four ways to fake infrared photography.
Regardless of your approach, this contrasty, unusual, B&W look is very refreshing and a nice way to shake things up.
