Following these steps will ensure that the calibration process is tailored to the specific display being used, allowing for accurate and precise calibration. This will result in improved image quality and color accuracy, providing users with an enhanced viewing experience. By utilizing the SDR calibration workflow template, users can optimize their display performance and stay up-to-date with the latest advancements in display technology.

Step 2

Upon opening the workflow template in the Calman Menu, users can proceed to the second step of the SDR calibration process for their Mac. In this step, the user needs to connect Patterns and their Meter. It is important to ensure that macOS and Calman are on the same network/subnet. The user can find available IP addresses in the Patterns menu and enter the IP address in the provided space. By clicking "Connect to Patterns," the user establishes a connection between Patterns and Calman. This step is crucial for the calibration process as it allows for the communication between the software and the display, enabling accurate measurements and adjustments.

Step 3

When configuring the workflow, the user needs to ensure that the colorspace settings for Pre-Calibration Validation are properly set to match the target colorspace and that the display is set to SDR mode for optimal performance. This can be achieved by following these steps:

• Set the target colorspace and Patterns colorspace to the same target.
• Set Patterns to Display SDR for optimal display performance.
• Disable Automatically Adjust Brightness and True Tone in macOS Display Preferences.
• Take pre-calibration measurements by clicking Read Series[] to measure grayscale and ColorChecker response.

By properly configuring the colorspace settings and ensuring the display is set to SDR mode, the user can accurately measure the pre-calibration state of the selected colorspace and proceed with the calibration process. This attention to detail and precision is essential in achieving the desired calibration targets and delivering innovative results.

Step 4

The next step involves measuring the pre-calibration state of the selected colorspace by utilizing the Read Series[] function to accurately capture the grayscale and ColorChecker response, ensuring precise calibration targets are established. This step is crucial in achieving optimal display performance. By clicking on the Read Series[] button, the software will measure the grayscale and ColorChecker response of the display. This measurement will provide valuable data that will be used to set the calibration targets. It is important to ensure that the measurements are taken accurately and consistently to achieve accurate calibration results. This step allows for the identification of any discrepancies or inaccuracies in the display’s color reproduction. By measuring the pre-calibration state, the calibration process can be tailored to address any issues and achieve the desired color accuracy and uniformity.

Step 5

To establish targets for calibration, the desired display calibration target and corresponding EOTF for native display response should be set, while ensuring that the Patterns colorspace matches the target colorspace. This step is crucial in achieving accurate and optimal calibration results. Here are some key considerations:

• Select the desired calibration target for the display.
• Choose the corresponding EOTF (Electro-Optical Transfer Function) that represents the native display response.
• Set the Patterns colorspace to match the target colorspace.
• For example, if the target colorspace is DCI P3 with D65 white point and a gamma of 2.2, the Patterns colorspace should be set accordingly, such as Photography (P3-D65 at 2.2).

By setting these targets, the calibration process can be tailored to the specific requirements of the display, ensuring precise color reproduction and accurate grayscale performance. This level of customization allows for the creation of visually stunning and innovative display experiences.

Step 6

Establishing targets for calibration involves adjusting the overall luminance of the display to achieve the desired level of brightness. To begin, click the "Read Continuous" button to measure the display’s light output at 100% white. Then, adjust the display’s peak white to the desired luminance level. If needed, target a higher luminance due to ambient light conditions. Additionally, adjust the backlight or brightness control for 15% brightness above the final target. This step ensures that the display’s luminance is optimized for accurate calibration. By fine-tuning the luminance, the display will provide a more precise and vibrant visual experience. It is crucial to consider the target luminance carefully as it significantly affects the overall image quality and accuracy of the calibration.

Step 7

In the previous step, we discussed adjusting the overall luminance of the display. Now, in Step 7 of the SDR calibration process with Patterns for Mac, we will perform the actual calibration to the selected targets. This step is crucial in achieving accurate and optimal display performance.

Here are the key actions to be taken in this step:

• Press the "AutoCal" button located in the lower right corner of the Calman interface.
• Name the ICC profile for easy identification on the AutoCal Setup Dialog.
• This will initiate the calibration process, where Calman will automatically adjust the display settings to match the desired calibration targets.
• The calibration process may take some time, depending on the complexity of the display and the desired targets.
• Once the calibration is complete, the display will be calibrated to the selected targets, ensuring accurate and consistent color reproduction.

By following these steps, you can achieve precise and reliable SDR calibration using Patterns for Mac, resulting in an enhanced viewing experience and improved color accuracy.
