NHK 11 gray scale test card (gamma = 0.45) mainly tests saturation. The gray scale represents the level of different brightness from darkest to brightest. The more intermediate levels, the more delicate the effect of the picture can be presented.

NHK 11 gray scale test cards (gamma = 0.45) are divided into two types: transmission and reflectance test charts. The transmittance and concentration of the two types of test cards are as follows:

Transmission

Step	1 (white)	2	3	4	5	6	7	8	9	10	11	Background
Transmittance (%)	74.1	61.7	50.1	40.7	31.6	23.4	16.6	12.0	7.6	4.5	2.0	22.4
Concentration	0.13	0.21	0.30	0.39	0.50	0.63	0.78	0.92	1.12	1.35	1.70	0.65

Reflectance

Step	1 (white)	2	3	4	5	6	7	8	9	10	11	Background
Reflectivity (%)	83.0	71.0	57.0	46.0	37.0	27.4	19.5	13.4	8.3	4.75	2.0	18.0
Concentration	0.08	0.15	0.24	0.34	0.43	0.56	0.71	0.87	1.08	1.32	1.70	0.74
