• Colour Grading: Provides a reliable guide for grading in post-production.

Why Use a Colour Calibration Tool in Filmmaking?

• Consistency Across Multiple Cameras: Ensures footage from different devices matches during editing.
• Accurate Skin Tones and Colors: Maintains lifelike representation for scenes with actors and nature.
• Time-Saving in Post-Production: Reduces guesswork in color grading and adjustment.

How to Colour Calibrate Using the ColorChecker Classic

Step 1: Setting Up the ColorChecker Chart

• Place the ColorChecker Classic Chart in your scene during the initial setup.
• Ensure the chart is well-lit with the same lighting conditions as your subject.
• Avoid direct reflections to maintain neutral readings.

Step 2: Capture Footage with the Chart

• Film a short clip or take a photo of the chart in your setup.
• Include the chart at the beginning of each setup or lighting change to ensure consistent calibration data.

Step 3: Import Footage into Editing Software

• Use professional software like Adobe Premiere Pro, DaVinci Resolve, or Final Cut Pro.
• Import the footage with the ColorChecker visible.

Step 4: Perform Colour Calibration

• Use the editing software's tools to match the ColorChecker patches to their corresponding values.
• For example, use the RGB Parade or Vectorscope to adjust highlights, midtones, and shadows.
• Tools like DaVinci Resolve offer dedicated color matching features that sync with the ColorChecker’s reference data.

Step 5: Apply Adjustments to the Entire Footage

• Once the footage with the ColorChecker is calibrated, apply the same settings across all clips from that scene.
• Ensure consistency in skin tones and environmental colors.

Step 6: Monitor Calibration

• For accurate display calibration, pair the ColorChecker Classic with a monitor calibration tool (e.g., Calibrite Display Pro).
• This ensures your editing screen represents colors accurately, preventing discrepancies in the final output.

Tips for Using the ColorChecker Classic

• Regularly Calibrate Your Camera and Monitor: Even the best equipment drifts over time. Routine calibration maintains reliability.
• Always Use the Chart in New Lighting Setups: Subtle lighting changes can affect colors dramatically.
• Pair with ColorChecker Software: Tools like the Calibrite Camera Calibration software enhance precision by generating custom profiles.
