Calibrating the Monitor Automatically
 
 
 

Use a colourimeter (an external monitor measurement device) to scan your monitor's output and automatically correct the display.

You should automatically calibrate the monitor at the beginning of each project. If the project is long, you may want to recalibrate the monitor from time to time. Every 200 working hours is a good guideline.

To work with film, using a colourimeter is strongly recommended to get the best results.

Gamma Calibration

You can calculate a gamma correction LUT using one measure. This creates a simple gamma curve.

To automatically calibrate the monitor based on a gamma measure:

  1. In the Calibrate menu, click Off to disable existing monitor calibration settings.

  2. Set the calibration type to Gamma.

  3. Attach the colourimeter to the centre of the screen.
  4. Enable Start.

    A series of grey patches appears on the screen. After a few moments, a monitor calibration LUT is generated based on the readings and saved to the monitor.calib file.

  5. Click Measured to apply the monitor calibration settings.

Curves Calibration

You can calculate the gamma correction LUT using a series of colours, which appears on the screen.

NoteYou can set the colour steps in the init.config file. See the Autodesk Lustre Software Installation Guide.

To automatically calibrate the monitor based on a curves measure:

  1. In the Calibrate menu, click Off to disable existing monitor calibration settings.

Reverting to a Previous Calibration Setting

If you are not satisfied with the results from the automatic calibration, you can revert to the previous automatic calibration.

To revert to a previous calibration setting:

  1. In the Calibrate menu, click Revert.

    The LUT that was previously saved to the monitor.calib file is used to calibrate the monitor. If you click Revert again, you will apply the settings from the latest LUT.
