It is quite feasible to use digital imaging to simulate the look of an image shot on infrared-sensitive film. However, this is no match for real digital infrared photography since you'll be working with an image that was taken in the visible spectrum!
While it requires some homework to find the right camera to use, true digital infrared photography can even resolve one or two of the problems associated with traditional infrared film photography.
One of them is that loading the film had to be done in the dark to avoid any stray infrared contamination. This is often impractical in the field.
Straightforward digital infrared photography can only be accomplished with older types of digital cameras which were built without an infrared cut-off filter over the imaging sensor.
Infrared sensitivity is inherent in all digital cameras due to the nature of the imaging sensors which they use to capture light.
This sensitivity can cause problems with their visible light images, and therefore a hot mirror filter is built over the sensor. This in turn makes it difficult to capture infrared light with such a standard camera.
To determine if your digital camera can detect infrared, you should place an infrared filter over the lens. Next take a source of infrared, such as your DVD or TV remote control and point it toward the camera.
If you can see the light through your viewfinder or on your LED screen, your camera is infrared ready!
An older digital camera such as the Konica-Minolta D'image 7 can be used after adding a 49mm IR filter and a cable release.
However, some cameras pass enough infrared light only through very long - and fairly impractical - exposures of between 2 and 30 seconds. This is done through infrared longpass filters over the lens.
For some photographers it makes sense to convert a suitable digital camera for digital infrared photography.
An example of a camera which can be effectively converted is the Nikon D70. In this case the filter can be installed over the imaging sensor instead of over the lens, which makes it possible for the image to be seen clearly in the viewfinder for easy composition.
It makes sense to leave this conversion to professionals to ensure it is done in a dust free situation - especially if your camera is still covered by a warranty!
Lastly, some of the ideal conditions for infrared photography:
- A bright day with blue sky and white cumulus clouds. Blue sky will turn dark & accentuate the white clouds.
- Green foliage are useful as the chlorophyll reflects infrared radiation, and therefore glows light gray.
