Not all digital cameras can shoot infrared unless they have modifications since most have various levels of infrared filtering. Fuji’s x100 is capable of capturing infrared with an R72 filter. First you need to do a custom color balance photographing green grass or other green foilage. For good depth of field it is recommended that you shoot at f/11 and try 3 too 4 second exposures. Obviously you will need a tripod and a cable release. You will be able to view the image area easily with the digital viewfinder or LCD on the back of the camera. (live view) The original image will appear very red, Here’s an example. The image below was exposed at f 2.8 at 1/20th of a second. I feel somewhat better results can be had with a smaller aperture which necessitates longer exposures.
When you convert the file to B&W it will appear real muddy. Adjust the levels to get proper contrast. You may also want to go into channels and make adjustments in the red channel.
The following images were exposed 4 secs at f/11.
