As I remembered this, I asked Claude to review what was the evolution of IR imaging with digital cameras and why:</p> <p>Digital cameras from the early 2000s would pick up near-infrared light with little effort — point a TV remote at the lens and the sensor would register the burst clearly. Attach a dark IR-pass filter and you could shoot striking infrared landscapes in reasonable exposure times. Modern phone cameras won&rsquo;t do any of this. The reason is a hardware filter, not a sensor limitation or a software restriction.</p>
