The images in this post were taken with my newly converted infrared camera. I sent my ancient Canon 300D (Digital Rebel) away to LifePixel to get it converted to infrared.
I chose the standard filter conversion which is equivalent to the classic Hoya R72 (a glass filter that is used in front of the lens of a non-converted camera). The resulting camera surgery results in very little visible light getting through to the sensor. The image straight out of the camera produces a redish tone, especially in the blues (like the sky). It can be converted in the Photoshop channels mixer so that the red channel is swapped for the blue. This produces a blue sky.
However, conversion to black and white produces a rich black sky and white foliage (all green becomes white in IR). There are a number of ways to do the conversion to black and white and I have been experimenting with a few. So far, I have discovered that I can get a fine image by using Silver Effects Pro. But first taking the photo into Photoshop and using levels and curves and then back into Lightroom for the Silver Effects conversion often works best.
Sometimes, I run Color Effects Pro on the image using the Pro Contrast filter. Other images do well with a touch of Topaz Adjust (the filter depends on the subject). I will be experimenting more and write about the results here.
