A second important unifying theme is an appreciation of the multiple dimensions of the visual experience of lightness brightness and transparency people do not perceive the lightness of surfaces by discarding information concerning the light illuminating those surfaces rather they perceive a pattern of illumination projected onto a . A second important unifying theme is an appreciation of the multiple dimensions of the visual experience of lightness brightness and transparency people do not perceive the lightness of surfaces by discarding information concerning the light illuminating those surfaces rather they perceive a pattern of illumination projected onto a pattern of surface greys. The past quarter century has witnessed considerable advances in our understanding of lightness perceived reflectance brightness perceived luminance and perceived transparency lbt this review poses eight major conceptual questions that have engaged researchers during this period and considers to what extent they have been answered. A second important unifying theme is an appreciation of the multiple dimensions of the visual experience of lightness brightness and transparency people do not perceive the lightness of surfaces by discarding information concerning the light illuminating those surfaces rather they perceive a pattern of illumination projected onto a pattern of surface greys
