Near-infrared photography captures, in pictures, reflected light that lies outside the visible light spectrum, or what humans can see Near-infrared light on the electromagnetic spectrum has wavelengths that are longer than visible light but slightly shorter than mid- or far-infrared11 Photosynthesizing plants absorb most visible light and reflect near-infrared light Thus, a near-infrared photograph can visually show areas with high or low degrees of photosynthesis, an indicator of plant health (Figures 46 and 47)12 The photographs can be taken with a near-infrared camera or by purchasing a kit to alter a traditional digital camera Post-processing software can be used on the photograph to analyze plant health1
