In work commissioned by VSCO, photographer Brea Souders captured some very unique images of popular food using a radiometric thermal camera.
The photos do a wonderful job displaying the fact that all matter with a temperature greater than absolute zero emanates electromagnetic waves.
Here’s an excerpt from VSCO that explains what’s happening in more detail:
A quality camera will record a specific temperature for each pixel in the image, with an accuracy of plus or minus 2 °C. Since the camera can detect minute differences in temperature and then assign a corresponding color to that temperature, relatively crisp images are rendered.
