Why Do Cameras “See Colors Wrong”? Have you ever noticed that two cameras capture the same scene with noticeably different colors? One of the main reasons lies in the light source used during production and testing. A camera’s “eyes” — its image sensors — are highly sensitive to light. If the spectral power distribution (SPD) of the test light source is unstable, the camera may misinterpret colors or brightness. That’s why controllable, spectrally stable light sources are essential in both camera production lines and laboratories. Among these, multi-channel spectrally tunable LED light sources are increasingly adopted by manufacturers and research institutions for their ability to accurately reproduce different spectra. ↑Two cameras capture the same scene with noticeably different colors.   Light and Camera Calibration: A Battle Between “Reality” and “Deviation” To enable a camera to see true color, several key aspects must be standardized: 1.Spectral Power Distribution (SPD) The spectrum is the “fingerprint” of light, defining energy across different wavelengths. If the spectrum deviates, red may appear pink, and blue may turn violet. → Therefore, camera calibration must be performed under a known and controllable SPD. 2.Color Temperature and Color Rendering You may have noticed how photos look warmer under…
