            Transfer characteristic curve:
            E = ((c1 + c2 * L^n) / (1 + c3 * L^n)) ^ m
            c1 = c3 - c2 + 1 = 3424 / 4096 = 0.8359375
            c2 = 32 * 2413 / 4096 = 18.8515625
            c3 = 32 * 2392 / 4096 = 18.6875
            m = 128 * 2523 / 4096 = 78.84375
            n = 0.25 * 2610 / 4096 = 0.1593017578125
                L - luminance of image 0 <= L <= 1 for HDR colorimetry.
                    L = 1 corresponds to 10000 cd/m2
                E - corresponding electrical signal}
