Setting up ambient light compensation properly

Why ambient measurement matters, where to put the ambient probe, and how to compensate without over-correcting.

What you will need

• A calibrated workstation
• A supported colorimeter (X-Rite, Calibrite, Datacolor, or QUBYX SmartSensor)
• QUBYX software installed and licensed

Step 1 — Baseline measurement

Take a baseline reading of the current display state before applying any calibration. Note ambient luminance and ambient reflection.

Step 2 — Apply the target

Pick the smart preset or custom target appropriate for the workflow. Apply calibration. Allow display warm-up if needed.

Step 3 — Verify and document

Run a verification pass against the applied target. Generate a PDF report. Archive with project metadata.
