Because IR light levels are very low you will need to use both a tripod and a slow shutter speed in order to get a sharp and well exposed shot. The use of software such as photoshop is not needed if you can get the correct exposure directly from the camera. One thing that will become clear is that in a colour exposure only red light is recorded, so if you intend to print directly to your printer then change your camera setting to black and white or set your printer for a monotone print.
