Why this tool is useful
A medium neutral gray is one of the most important screens for calibrating monitor brightness and gamma. A correctly calibrated display should render this at exactly 50 percent of the screen peak brightness with no perceptible color cast. Photographers and print professionals use gray screens as a baseline check every morning before beginning editing sessions to confirm that overnight ambient temperature changes have not affected display performance.
