Document Summary

We tend to perceive the world with our preconceptions: perceptual constancy the process where we perceive stimuli consistently across varied conditions. Seeing: the human visible spectrum wavelengths of light, brightness the intensity of the reflected light that reaches our eyes, hue the colour of light (red, green, blue) Addictive colour mixing mixing any colours. Subtractive colour mixing mixing any colours in paint or ink: the eye, sclera the white of the eye, iris the coloured part of the eye the eye. Chemical responsible for the eye pigments: pupil circular hole where light enters the eye, cornea a curved, transparent layer covering the iris and pupil. Rods long and narrow receptor cells that enable us to see basic shapes and forms (rhodopsin chemicals that change following exposure to light) Cones colour vision: fovea central part of the eye; responsible for acuity (sharpness of vision)
