PSYB51H3 Chapter Notes - Chapter 5: Intrinsically Photosensitive Retinal Ganglion Cells, Subtractive Color, Circadian Clock
Document Summary
Recall that humans see wavelengths of appx 400 and 700 nanometers (nm) Most of the light that we see is reflected light. The more light that;s absorbed, the darker the surface will appear. We want those perceived colors to go w the object (that rose looks red) and not to change dramatically as the viewing conditions change (that rose should remain red in the sun and shadow) Cone can detect that wavenelth as well their spectral sensitivities overlap. = referring to the sensitivity of a cell or a device to diff wavelengths on the electromagnetic spectrum recall that s cones are rare & are less sensitive that m-cones and. L-cones the combination of sensitivities of the 3 types of cones gives us our overall ability to detect wavelengths from about 400nm to about 700nm recall that cones work in the daylight (phtopic) light levels.
