Using with other options
You can combine brightness with other tone controls (e.g., hue, saturation) for more precise adjustments.
Small changes (e.g., 1.05–1.15) are often enough to make a noticeable difference.
Very high or low values may blow out highlights (too bright) or crush/lose detail, so it’s best to adjust gradually.
