FLIR Thermal80×60 Thermal, Iron Palette

FLIR (Forward-Looking Infrared) thermal cameras detect heat radiation invisible to the human eye, creating color-mapped images where temperature differences appear as vivid gradients. Originally developed for military and industrial use, compact thermal cameras became available for smartphones around 2014. The distinctive 'iron palette' — ranging from deep blue (cold) through red to white (hot) — has become an iconic visual style.

RetroCam recreates this look using real optical data: color temperature curves, aberration profiles, grain structure, and tonal response. The result is a live camera effect that feels authentic, not just a filter slapped on top.
