Having accurate color is essential for any digital cinema workflow. Uncalibrated displays give a false representation of the image, which turns color-precision into guesswork. The colors from a device can also drift over time, making it important to re-calibrate regularly to ensure accuracy.
The calibration process includes: Adjusting display settings for a Quick Profile, performing Basic or Advanced Calibration, final colorspace verification, and a detailed device report.
A custom ICC Profile (International Color Consortium) is created which can be applied at the operating system level. This ensures an accurate gamma and white-point across all applications.
For color-critical work, a larger data-set of colors are collected, from which a full 3D LUT (Look-up Table) can be generated. With the ability to balance hue and saturation in addition to gamma and white-point, a 3D LUT delivers the highest level of color accuracy possible.
The above images use actual calibration data to illustrate the differences between an ICC Profile (Basic) and a 3D LUT (Advanced). As can be seen, the ICC Profile is able to balance the monitor’s white-point and gamma, but only the 3D LUT can achieve accuracy across the color spectrum – within the display’s limitations.
|Common Display Types||Delivery Format||Output Colorspace|
|Laptops & Computer Monitors||Delivery Format: Web & Mobile||Output Colorspace: sRGB|
|HDTVs, Projectors||Delivery Format: Broadcast||Output Colorspace: Rec709|
|Cinema Displays & Cinema Projectors||Delivery Format: Theatrical||Output Colorspace: DCI-P3|
All computer-based devices use ICC Profiles. For Advanced Calibration, the display needs to support 3D LUTs, otherwise additional software or hardware (3D LUT Box) will be required to apply the calibration data.
Common connection formats include: HDMI, Thunderbolt, DVI, Display Port, HD-SDI, VGA, and RCA. The type of connection format may affect the calibration time.
|Calibration Type||Deliverable||Time Estimate||General Pricing|
|Basic Calibration||Deliverable: ICC Profile||Time Estimate: 20-45 minutes||General Pricing: $225 per display|
|Advanced Calibration||Deliverable: 3D LUT||Time Estimate: 60-200 minutes||General Pricing: $375 per display|
