If a visual system only made a single measurement of luminance acting as a pho tometer then there would be no way to distinguish a white surface in dim light from a black surface in bright light et humans can usually do so and this skill is known as How does our body construct our conscious visual experience? . How de we transform particles of light energy to another? . We do this by receiving light energy and transforming it into neural messages that our brains process into what we consciously see..
