What causes infrared radiation? Heat, the same stuff the new Webb Space Telescope registers. Some of us photography nuts get an old camera body modified with an infrared sensor and go out to do our own research on what the eye cannot see.
Saturday was tied for the hottest of recent days (Sunday got to 104 F / 40 C, too). I went out driving around, leaving the car as little as possible, to see what I could capture. Green foliage reflects infrared like crazy and looks white in a photo. There are a couple of specific Photoshop techniques to adjust the other colors. This is the pagoda on an island in Forest Park. More to come.
Never tried that. Enjoy. Stay cool.
