I want to simulate a real image captured by an infrared camera under an infrared light source illumination. The length of infrared wavelength is 850nm. How does we do such experimentation on blender. Is it possible to do it?
Tristimulus models such as RGB are effectively a wide band visible spectral light emulation, making such experiments impossible.
Even spectral based renderers might have a hard time with spectral rendering when dealing with non-visible infra red or ultra violet, depending on how they have been designed.
