I do not have access to any Gamma correction property, but I should be able to measure its effects with calibration (basically I expect not to find perfect linearity but I can fit an exponential law to find gamma). Exposure is fixed. As for the actual counts and saturation, should I check the red channel only or the 3 channels? As I said the camera software can desaturate the image, but I am not sure how it mixes the 3 channels. | |
