Infrared Light’s Infrared Discovery Light

Infrared Light This area had the highest INFRARED temperature reading of all, Herschel measured Infrared despite being invisible to the temperature Light the naked eye. beyond the red- He named this radiation colored light, where ‘calorific rays.’ there was no sunlight.

Today we call it INFRARED Near infrared light is in the “Infra” is a Latin prefix range of 700nm-1100nm; Infrared meaning ‘below.’ Ranges visible, 380nm-700nm Light INFRA-RED = radiation of Light Night-vision goggles or below red in terms of light infrared cameras allow us to

Why Camera Conversion How It’s Done

Your camera’s light blocking filter must be converted to “see” infrared light / radiation.

No Custom WB? General Suggestions

•Shoot in RAW •Use histogram on the LCD, and when •Set your white balance on Auto processing, to refine your exposure. •Use the camera’s proprietary processing •Sometimes overexposure may be part of software to manage the output, instead of your vision. Keep that in mind. Photoshop or Lightroom.

Seeing in Infrared

The magic of Infrared photography is in the contrast of lights and darks, as well as the frequently soft, surreal effects. Deciduous leaves, grasses, generally water plants — any elements in nature that emit infrared radiation — will capture as white. When composing your image, pay Seeing in Infrared attention to the flow and interaction of the lights, darks and values. Conifers, rocks, dirt, tree trunks, buildings, water, blue sky — any elements not emitting warmth — capture as darks. Learn to see the differences and compose with these characteristics in mind.
