The Answer to How Light Is Perceived
Simply put, photometry is the measurement of visible light based on the response of the average human observer. How that definition translates into technically correct quantification methods is the focus of this article. That portion of the spectrum that the eye can see — and its rainbow of colors — is rather small, covering approximately 360 to 830 nm. What colors we perceive depends on wavelength, while the amount of light energy detected by the eye at a particular wavelength...
