Problem
Bright gradient backgrounds clip before the main subject is properly exposed.
Solution
Root Cause / Diagnostic:
Overly luminous background gradients (RGB > 245) pull viewer attention away from the creator's face due to extreme luminance weighting. Furthermore, over-bright backgrounds cause adjacent subject skin highlights to appear muddy or underexposed by comparison.
Actionable Fix:
1. Compress background highlight levels using an Output Levels ceiling of 230–235, leaving peak luminance reserved exclusively for core hook elements.
2. Boost the subject's facial exposure by +0.5 to +1.0 EV with a localized Curves adjustment to re-establish the face as the primary luminance anchor.
3. Evaluate the thumbnail using a luminance heatmap to confirm the subject's face is the brightest organic element on the canvas.
Pro Tip:
Cap background brightness at 90% luminance; reserving pure 100% white for headline text and facial catchlights guarantees subject dominance.
