Infrared, don’t accept any substitutes.
I went for a walk today with my Sony DSC-V3 which I use mostly for infrared photography. There are software filters that purport to giving an IR effect to photo’s but really they are still manipulating the visible light that was captured. Here is a scene shot in colour and IR as well as a version created in Photoshop from the colour photo to mimic Kodak HIE. I obviously prefer the last one, the actual IR shot or I wouldn’t continue to use the camera in this way.
The actual method is to set the camera on night shot mode, which internally moves an IR blocking filter out of the imaging path. This allows both Infrared light and visible light to reach the sensor. The visible light however is blocked by a Rodenstock RG715 filter that as it’s name suggests cuts off light transmission bellow 715 nanometers. A ND8 filter is also used to cut down on the amount of light reaching the sensor. These filters are held in front of the camera in an assemblage of adapters and filters.
Here are some more IR pictures from today.
And This last image which came about when I pointed the camera at the huge furnace in the sky while not in nightshot mode.
