Brightness calibration techniques

Brightness calibration involves adjusting a display to show images accurately by ensuring its brightness levels match standard reference values. Techniques include using a calibration device called a colorimeter or spectrophotometer to measure screen luminance, then adjusting settings like backlight, contrast, and gamma to achieve consistent results. Software calibration tools guide users through these adjustments, often referencing standardized test patterns or target brightness levels. This process ensures that the display shows images with proper brightness and contrast, which is crucial for tasks like photo editing or color grading, leading to more accurate and consistent visual reproduction across different devices.
