WHITE BALANCE CHART (70% REMISSION)
The TE115 chart is designed for white balance. The density of the white area is 0.15 (based on
BaO 4S=0). This corresponds to a remission of 70%.
The material which is used for the white chart shows high
homogeneity of the remission in the
visible spectrum of 380 to 700nm (see gray curve in the
illustration). In the area below 420 the
remission shows a steep decrease. In this area the sensitivity of
the blue and red functions is
so low, that the light reflected is not transformed significantly.
