We keep hearing about infrared light as a part of new products being introduced in a number of different fields. This source of energy is able to perform much better than older technologies in a broad range of functions.
Infrared light is electromagnetic radiation waves that have longer wavelengths than that which we see in visible light. This is similar to most of what we get from the sun. Scientists have figured out ways in which that energy can be used in all types of industries, including industrial, scientific, and medical applications. It is also used in many consumer products.
In photography, film and image sensors are sensitive to infrared light, and the part that is used is referred to as near-infrared. Far infrared is the domain for thermal imaging. The wavelengths used will range from about 700 to 900 nm. Since film is typically sensitive to visible light, an infrared passing filter must be used that allows the waves to pass through to the camera, but blocks the light spectrum.
These filters allow you to create incredible effects in your photography such as false color or black and white. There is also an appearance that is known as the wood effect, which is cause from the light reflecting off of leaves or blades of grass. You will also find that with infrared filtering you are treated to darker skies in your photos and atmospheric haze.
Other Uses For Infrared Light
Because of its longer wavelengths, infrared light is more powerful than regular light, and that energy is being harnessed in a number of ways. One that is growing in popularity, and great for at home relaxation, is the at-home sauna. The long waves are able to penetrate deeper into the skin, giving you a more thorough cleansing than a traditional sauna.
Since these are portable devices, you can enjoy the full on benefits of a spa sauna, without it taking up too much space in your home. If you are interested in learning more about portable infrared saunas and how they work, visit a review site like www.saunainsider.com and see what people who use them have to say.
If you are interested in expanding your knowledge of photography, and its applications, infrared light is one valuable tool to incorporate. Experiment with various filters and lighting techniques and you will find that you are able to develop incredible images that your subjects will love.
