1 - Chart Color Calibration - Using a Macbeth Chart

This calibration method uses the 24-patch Macbeth chart. It is useful in cases where spectral data is not available for your target sensor or the IR filter on the lens. It allows calibration of the low color temperature (Left) and high color temperature (Right) matrices individually. Sensors supporting a separate matrix for flash photography can be calibrated for flash as well.

Basic Calibration Steps

Basic calibration steps are:

1. Place a 24 patch Macbeth chart in a properly illuminated location. The color temperature has to match the Illuminant selection for the specific matrix which is being calibrated. We strongly recommend using a light booth for this step.
2. Adjust the sensor gains so that the bottom chart patches are white balanced, as shown in the image below. The low left patch RGB color values need to be at approximately 220.
   
3. Once the sensor gains have been adjusted either save the image into a file and load it into SensorTune, or use SensorTune option to directly load the image from DevWare.
4. Press the Calculate button
