YE0115 test chart is specially designed for white balance test.
The density of the white area is 0.15 (based on BaO4S = 0).
The corresponding reflectivity of the white balance test card is 70%.
The white balance test card is made of highly homogeneous materials in the visible spectrum of 380-700 nm (see the grey curve in the illustration). In the 420 area of the slow downward trend in the figure below, a sharp downward waveform appears. The sensitivity of blue and red in this area is low, and the reflection of light has not changed significantly.
