False Colour or True Infra-red

Personally I prefer to process my digital infra-red images to have a similar look and feel close to what was achieved when using conventional High Speed Infra-red Film. These were monochrome images with a fair amount of grain, slightly diffused and a little soft on focus. However, there are some infra-red photographers, who disagree and choose to display their work by leaving them in colour. As with any type of photography the option to shoot monochrome or colour will depend on the subject matter, you still have that choice.

How much colour you choose to leave in your Infra-red images will depend on the type of Infra-red filter you use. The most popular Infra-red filter is the R72. This filter has a 720nm rating, which will block out a fair amount of visible light, but not all of it, hence the colour creeping into your image.

If you wish to capture a more traditional Infra-red image I would recommend using a stronger, more opaque filter of around 750nm or higher. A 750nm filter will block out 99% of normal light therefore, letting more Infra-red light waves through, leaving you with a more traditional looking Infra-red image.

If you are considering have your camera converted? Choose the type of filter you want fitted wisely before going ahead with the conversion.
