F\u00f6rh\u00e5llandet \u0394 L\/L1 i ekvationen \u00e4r k\u00e4nt som Webers br\u00e5k, som beskriver den minsta detekterbara skillnaden i luminans. Detta hj\u00e4lper till att best\u00e4mma den perceptuella k\u00e4nsligheten f\u00f6r f\u00f6r\u00e4ndringar i ljusstyrka. I vissa fall, n\u00e4r endast reflekterande ytor \u00e4r inblandade, kan luminanskontrast uttryckas i termer av reflektans. Reflektans avser f\u00f6rh\u00e5llandet mellan ljus som reflekteras av en yta och det infallande ljuset som faller p\u00e5 den. Kontrastformeln med reflektans \u00e4r (\u03c11 \u2013 \u03c12)\/\u03c11 eller (\u03c12 \u2013 \u03c11)\/\u03c11, d\u00e4r \u03c11 och \u03c12 representerar reflektanserna f\u00f6r bakgrunden respektive objektet. Metoden f\u00f6r att ber\u00e4kna kontrast med hj\u00e4lp av reflektans g\u00e4ller endast f\u00f6r perfekt diffusa ytor. F\u00f6r andra ytor m\u00e5ste ytterligare faktorer som infallsvinklar och siktvinkel beaktas.<\/p>
