Playing with an Infrared Camera
A simple phone attachment reveals the invisible thermal world, from warm cheeks to cold footprints.
Deep Dive
A blogger uses a phone-attached infrared camera, initially for a house project, to explore thermal properties with his children. They observe body heat patterns, see 'heat fingerprints' left on surfaces, and identify heat loss in buildings. The device turns everyday objects into thermal maps, revealing hidden details like wall studs. The author notes the potential for combining multiple infrared images with modern processing for higher-quality results.
