Look for subjects with interesting textures, such as foliage, water, or architecture, as these objects will appear drastically different in infrared.
Understanding Infrared Light
Infrared light is a type of electromagnetic radiation that is invisible to the human eye but can be detected by certain digital camera sensors. It falls in the wavelength range of 700 nanometers (nm) to 1 millimeter (mm), just beyond the red end of the visible light spectrum.
Understanding the properties of infrared light is important for successful infrared photography. Infrared light behaves differently than visible light, making it an intriguing subject for photographers.
How Infrared Light Differs from Visible Light
While visible light is easily reflected, absorbed, or transmitted by various objects, infrared light interacts differently. Infrared light is mostly reflected by plants, making them appear bright and vibrant in infrared photographs. This reflection is due to the high concentration of water in plants, which absorbs visible light but reflects infrared light.
On the other hand, materials such as glass and plastic that are transparent to visible light can block or absorb infrared light. This is why photographers using infrared techniques often notice that infrared images show less reflection from windows or other transparent surfaces compared to visible light images.
Applications of Infrared Photography
Infrared photography has various applications beyond artistic expression. The unique characteristics of infrared light make it useful in fields such as aerial mapping, scientific research, and even in the detection of hidden thermal energy. Infrared sensors can capture temperature differences, helping identify anomalies in electrical systems, locate energy leaks in buildings, and even diagnose certain medical conditions.
By understanding the fundamental properties of infrared light, photographers can explore the creative possibilities it offers and take unique and captivating images.
