Most digital cameras incorporate an infrared blocking filter in front of their sensor to remove this longer wavelength, so not all cameras can be used for recording this hidden world. Because infrared wavelengths are longer than visible light they also bend at a different angle when passing through the lense so we must readjust the focusing when shooting infrared images (focus closer than normal). A special filter is used to block all visible light and only allow the longer near infrared wavelengths to be recorded.
Not all Infrared images show heat. The ones which do are called thermal infrared images and are generated by recording radiation much farther down the spectrum (longer wavelengths) than the images recorded by consumer or professional near infrared capable cameras.
False colour infrared composites are generated by showing the Green parts of the image as Blue, the Red parts as Green and the newly acquired Near Infrared information as Red. This composite often shows vegetation as Red due to its high amount of reflected infrared radiation.
