There is, Adobe DNG SDK suggests one way to approximate it, and there are other ways, too. With Canon one can do interpolation as the raw files contain data like this: 10900, {2.92571f, 1.0f, 1.25183f, 1.0f}, 10000, {2.86034f, 1.0f, 1.28160f, 1.0f}, 8300, {2.70185f, 1.0f, 1.36533f, 1.0f}, 7000, {2.53465f, 1.0f, 1.46705f, 1.0f}, 6000, {2.36490f, 1.0f, 1.57538f, 1.0f}, 5600, {2.28062f, 1.0f, 1.63578f, 1.0f}, 5200, {2.18337f, 1.0f, 1.70383f, 1.0f}, 4700, {2.06452f, 1.0f, 1.81883f, 1.0f}, 4200, {1.92120f, 1.0f, 1.96923f, 1.0f}, 3800, {1.78397f, 1.0f, 2.11570f, 1.0f}, 3500, {1.67320f, 1.0f, 2.26549f, 1.0f}, 3200, {1.54683f, 1.0f, 2.45564f, 1.0f}, 3000, {1.46286f, 1.0f, 2.63239f, 1.0f}, 2800, {1.36533f, 1.0f, 2.79781f, 1.0f}, 2400, {1.16232f, 1.0f, 3.21003f, 1.0f} On 12/5/22 23:00, Jeff Nova via colorsync-users wrote:
