Visible light is a small but extraordinary slice of the electromagnetic spectrum, located between infrared and ultraviolet light. It spans wavelengths from approximately 380 to 750 nanometers, corresponding to frequencies of about 400 to 790 terahertz (THz). This range encompasses the vibrant colors we see, from radiant red to deep violet. Visible light is not just a marvel of nature but also the foundation of photography, transforming light into stories, emotions, and memories. Every image celebrates this incredible interplay of energy, color, and frequency.
